SAFETY CONSIDERATIONS Installation and servicing of air-conditioning equipment can be hazardous due to system pressure and electrical components. Only trained and qualified service personnel should install, repair, or service air-conditioning equipment. Untrained personnel can perform basic maintenance functions of cleaning coils and filters and replacing filters. All other operations should be performed by trained service personnel. When working on air-conditioning equipment, observe precautions in the literature, tags and labels attached to the unit, and other safety precautions that may apply. Follow all safety codes. Wear safety glasses and work gloves. Use quenching cloth for unbrazing operations. Have fire extinguisher available for all brazing operations.

It is important to recognize safety information. This is the safety- alert symbol . When you see this symbol on the unit and in instructions or manuals, be alert to the potential for personal injury. Understand the signal words DANGER, WARNING, CAUTION, and NOTE. These words are used with the safety-alert symbol. DANGER identifies the most serious hazards which will result in severe personal injury or death. WARNING signifies hazards which could result in personal injury or death. CAUTION is used to identify unsafe practices, which may result in minor personal injury or product and property damage. NOTE is used to highlight suggestions which will result in enhanced installation, reliability, or operation.

WARNING

Open all remote disconnects before servicing this equipment. Failure to do so could result in personal injury from electric shock.

DANGER

DO NOT USE TORCH to remove any component. System contains oil and refrigerant under pressure. To remove a component, wear protective gloves and goggles and proceed as follows: a. Shut off electrical power to unit. b. Recover refrigerant to relieve all pressure from system

using both high-pressure and low pressure ports. c. Traces of vapor should be displaced with nitrogen and

the work area should be well ventilated. Refrigerant in contact with an open flame produces toxic gases.

d. Cut component connection tubing with tubing cutter and remove component from unit. Use a pan to catch any oil that may come out of the lines and as a gage for how much oil to add to the system.

e. Carefully un-sweat remaining tubing stubs when neces- sary. Oil can ignite when exposed to torch flame.

Failure to follow these procedures may result in personal inju- ry or death.

WARNING

UNIT OPERATION AND SAFETY HAZARD Failure to follow this warning could cause personal injury, death and/or equipment damage. R-410A refrigerant systems operate at higher pressures than standard R-22 systems. Do not use R-22 service equipment or components on R-410A refrigerant equipment.

STORAGE RECOMMENDATIONS The 38AP condensing units are designed for outdoor installations. At times, a delay in construction or other factors require that a unit be stored for a period of time prior to installation. The following guidelines should be used for unit storage.

Provide Machine Protection Place and store the unit in an area that will protect it from vandal- ism, accidental contact with vehicles, falling debris or construction waste. Ideally, do not remove the shipping protection such as the coil protectors. This will provide additional protection for the unit. The unit can be stored outdoors.

Inspection During Storage To ensure faster installation when the time comes, the following inspection schedule is recommended: EVERY 3 MONTHS The 38AP units are shipped with a nitrogen holding charge. Check each refrigerant circuit to be sure that there is positive pres- sure, at least 5 psig (34.5 kPa) in the circuit. If a circuit is found to be without pressure, contact a qualified refrigeration mechanic. The system should be pressurized to find the leak. It should be re- paired, dehydrated and recharged with nitrogen. If a positive cir- cuit pressure was not found, the compressor oil should be changed or at least sampled to determine if moisture is present. If moisture is found in the compressor oil, the oil should be changed. EVERY 6 MONTHS Check the unit for damage from any source. Check the unit for nests from rodents, birds, or insects. Depending on location, these organisms can cause deterioration of components which may re- sult in failure. Consider an exterminator if necessary. If damage is found that will interfere with the installation, consider repairing the damage before installation. Check the unit control box for signs of moisture. If moisture is found, determine the entry path and seal the leak.

INSTALLATION

Step 1 Inspect Shipment Inspect unit for damage upon arrival. If damage is found, im- mediately file a claim with the shipping company. Verify prop- er unit delivery by checking unit nameplate data and the model number nomenclature shown in Fig. 1. See Tables 1 and 2 for unit physical data.

Step 2 Rig and Place Unit All units are designed for overhead rigging, and it is important that this method be used. Lifting holes are provided in the frame base rails. It is recommended to use shackles in the lifting holes (see rigging label on the unit and Fig. 3 and 4 for rigging weights and center of gravity). All panels must be in place when rigging.

Use spreader bars or frame to keep the cables, chains, and straps clear of the unit sides. Leave standard coil protection packaging in place during rigging to provide protection to coils. Remove and discard all coil protection after rigging cables are detached.

DOMESTIC UNITS Standard 38AP unit packaging consists of coil protection only. Skids are not provided. If overhead rigging is not available at the jobsite, place the unit on a skid or pad before dragging or rolling. When rolling, use a minimum of 3 rollers. When dragging, pull the pad or skid. Do not apply force to the unit. When in final posi- tion, raise from above to lift unit off the pad or skid. EXPORT UNITS All export units are mounted on skids with vertical coil protection. Leave the unit on the skid until it is in final position. While on the skid, the unit can be rolled or skidded. Apply force to the skid, not to the unit. Use a minimum of 3 rollers when rolling. When in fi- nal position, raise from above to remove the skid. PLACING UNITS When considering location of the unit, be sure to consult National Electrical Code (NEC, U.S.A.) and local code requirements. Al- low sufficient space for airflow, wiring, piping, and service. The placement area must be level and strong enough to support the op- erating weight of the unit. (See Table 3 and Fig. 2.) When unit is in proper location, use of mounting holes in base rails is recommend- ed for securing unit to supporting structure. For mounting unit on vibration isolators, 4 x 24 in. perimeter support ASTM C chan- nels between unit and the isolators are recommended with a mini- mum of 4 channels per unit. Fasteners for mounting unit are field supplied. See Fig. 5. Refer to Fig. 6-10 for airflow clearances. Recommended mini- mum clearances are 6 ft (1829 mm) for unrestricted airflow and service on sides of unit, 4 ft (1219 mm) on ends, and unrestricted clear air space above the unit. Provide ample space to connect liq- uid and suction lines to indoor unit. For multiple units, allow 10 ft (3048 mm) separation between airflow surfaces. If walls surround the unit, wall height should not exceed the top of the unit fan dis- charge. Installation in a pit is not recommended.

CAUTION

DO NOT re-use compressor oil or any oil that has been ex- posed to the atmosphere. Dispose of oil per local codes and regulations. DO NOT leave refrigerant system open to air any longer than the actual time required to service the equipment. Seal circuits being serviced and charge with dry nitrogen to prevent oil contamination when timely repairs cannot be com- pleted. Failure to follow these procedures may result in dam- age to equipment.

IMPORTANT: To maintain unit stability while lifting, use 4 cables, chains or straps of equal length. Attach one end of each cable to shackle attachment point and the other end of each cable to the overhead rigging point.

CAUTION

All panels must be in place when rigging. Failure to comply could result in equipment damage.

CAUTION

For unit sizes 025 to 060 when handling with a forklift, handle only through fork pocket holes. Failure to follow this caution could result in equipment damage or personal injury.

CAUTION

For unit sizes 065 to 130, do not forklift the unit unless unit is attached to a skid designed for forklifting. Failure to follow this caution could result in equipment damage or personal in- jury.

IMPORTANT: Be sure to mount unit level to within 1/8 in. per ft (10.4 mm per m) to ensure proper oil equalization between compressors.

NOTES: 1. All piping must follow standard refrigerant piping techniques. Refer to Carrier System

Design Manual for details. 2. All wiring must comply with the applicable local and national codes. 3. Wiring and piping shown are general points-of-connection guides only and are not

intended for, or to include all details for, a specific installation. 4. Install field-supplied disconnect switch in accordance with all local and national electrical

codes. 5. Liquid line solenoid valves may be required for charge management depending on unit

size and evaporator size. Valves open with temperature differential, when OAT is less than SST.

6. Factory-supplied accumulator not shown. 7. Dual-circuit piping shown. Single-circuit piping is similar but would only have one suction

line and one liquid line. 8. Inverted trap on single suction riser not required if suction line is pitched in direction of

refrigerant flow. Inverted trap is required on all double suction risers. 9. A field-supplied (min. 5% up to 15%) bleed port TXV is required for every application.

10. Sight glass, LLSV, and filter drier are field supplied. 11. Long line length check valves are required for liquid line installation on all linear line

length applications of more than 100 ft (30.5 m). For any 025-030 size dual-circuit unit application where evaporator is located higher than the condensing unit, check valves are required for linear line length above 55 ft (16.8 m).

12. Do not use soft solder.

Step 3 Make Refrigerant Piping Connections

The units have large suction lines to minimize friction losses. The units also have the ability to operate at low capacity. Because of these capabilities, use special care with suction piping and suction risers to ensure proper compressor oil return under all operating conditions. If the evaporator is above the condensing unit, the maximum allowable vertical separation between the condensing unit and the evaporator is 75 ft (22.9 m) for all units. Size suction lines in accordance with Table 5 (60 Hz) or Table 6 (50 Hz), and Fig. 14.

SIZE REFRIGERANT LINES Consider the length of piping required between the condensing unit and indoor unit (evaporator), the amount of liquid lift, and compressor oil return. Suction and liquid lines should be sized in accordance with Table 5 (60 Hz) or Table 6 (50 Hz). Double suc- tion risers may be required if condensing unit is located above the evaporator to assure proper oil return at minimum load operating conditions. See Fig. 14. Note the indoor unit installation instruc- tions for additional information.

Fig. 14 Double Suction Riser Construction

CAUTION

Do NOT bury refrigerant piping underground. Failure to com- ply could result in equipment damage.

CAUTION

The field-supplied liquid line solenoid valve must be installed at the evaporator to avoid possible compressor damage during unit operation if the maximum allowable evaporator size is ex- ceeded per Tables 7 and 8. See Fig. 15 (for 38APD025-130 dual-circuit units), or Fig. 16 (for 38APS025-065 single-circuit units).

*Equivalent Length shown is based on the Total Linear Length plus an additional 50% for fittings and valves. If application requires more than 50% additional losses for fittings and valves, calculate the equivalent length and find pipe size using the Equivalent Length columns.

NOTES: 1. Shading indicates double suction riser or reduced riser is required

on circuit where suction gas flow is up. 2. Suction and liquid line sizing is based on pressure drop equivalent

to 2F (1.1C) at nominal rating conditions.

*Equivalent Length shown is based on the Total Linear Length plus an additional 50% for fittings and valves. If application requires more than 50% additional losses for fittings and valves, calculate the equivalent length and find pipe size using the Equivalent Length columns.

NOTES: 1. Shading indicates double suction riser or reduced riser is required

on circuit where suction gas flow is up. 2. Suction and liquid line sizing is based on pressure drop equivalent

to 2F (1.1C) at nominal rating conditions.

3. All pipe sizes are OD inches. Equivalent sizes in millimeters follow:

LIQUID LINE SOLENOID VALVE Field-supplied liquid line solenoid valve(s) are used for refrigerant charge management and in some cases oil return. Generally, one solenoid valve for each refrigeration circuit is recommended and must be installed at the evaporator if coil surface area is exceeded per Tables 7 and 8. In some cases, evaporator coil tons/circuit is too low to properly entrain oil while the circuit is operating at less than full load. In these cases, additional solenoids may be re- quired. Contact the evaporator coil manufacturer/supplier for in- formation on circuit loading and the need for additional solenoids. Install liquid line solenoid valve just ahead of the TXVs (thermo- static expansion valves) which will be mounted at the evaporator. See Fig. 15 (for 38APD025-130 dual-circuit units), or Fig. 16 (for 38APS025-065 single-circuit units). Refer to Table 4. EVAPORATOR SUCTION HEADER PIPING To ensure proper oil return, individual suction line connections at the evaporator coil must be sized properly. See manufacturers recommendations. THERMOSTATIC EXPANSION VALVES All 38AP units must be installed with 5% up to 15% bleed port TXVs to ensure proper unit operation. To achieve good mixing of the refrigerant leaving the evaporator suction header for proper sensing by the TXV bulb: 1. Install a minimum of two 90-degree elbows upstream of

the TXV bulb location. See Fig. 16 for dual-circuit units and Fig. 17 for single-circuit units.

2. Locate the TXV bulb on a vertical riser, where possible. If a horizontal location is necessary, secure the bulb at approximately the 4 oclock position.

3. Insulate TXV bulb to minimize external ambient effects. If an oil return connection is located at the bottom of the evapora- tor suction header, tee-in this connection ahead of first mixing el- bow. See Fig. 17 for dual-circuit units with face split coils, Fig. 18 for single-circuit units with face split coils, Fig. 19 for dual circuit units with row split coils, or Fig. 20 for single circuit units with row split coils. When the compressor is below the evaporator, the riser at the evaporator should extend to the top of the evaporator section. After the riser is installed, the suction line can elbow down immediately. Refer to the evaporator product data for sizing information. LIQUID LINE FILTER DRIER Installation of a field-supplied filter drier and sight glasses in each refrigerant circuit is required. Select the filter drier for maximum unit capacity and minimum pressure drop. Figure 15 (for dual-cir- cuit units) or Fig. 16 (for single-circuit units) shows required loca- tion of solenoid valves and recommended locations for the filter driers and sight glasses. Complete the refrigerant piping from the evaporator to the condenser before opening the liquid and suction lines at the condenser. Refer to Table 4.

LONG LINE APPLICATIONS A long line option kit must be installed for: 1. Any 025-030 size dual-circuit unit where the evaporator is

located higher than the condensing unit and the linear line length exceeds 55 ft (16.8 m).

2. Any size dual or single-circuit unit with linear line length of 100 ft (30.5 m) or more.

The kit consists of a liquid line check valve and a bypass check valve to prevent charge migration to compressor. The long line op- tion kit must be mounted in the liquid line near the condensing unit. The kit may be mounted in any orientation, horizontally or vertical- ly. See Fig. 21 for orientation and Fig. 12 for location. If a long line check valve assembly is used, a refrigerant access port downstream of the assembly must be provided to facilitate evacuation. HOT GAS BYPASS Hot gas bypass is not recommended. If hot gas bypass is used, it should be introduced before the evaporator. FINAL CONNECTION AND LEAK TEST

Relieve the pressure caused by the nitrogen holding charge. Con- nect liquid line and suction line to field piping. Refer to Fig. 6-10 for circuit orientation.

The refrigerant system must not be opened and exposed to atmo- sphere for longer than 15 minutes. Connection and pumpdown should be made as soon as possible to avoid acids forming in the compressor POE (polyolester) oils, which could damage the com- pressors. Leak test the entire system by using soap bubbles and nitrogen or R-410A and an electronic leak detector. Purge nitrogen or recover R-410A from system after completion of leak-checking procedure. Repair leak if one is found. When fin- ished, evacuate and dehydrate system using the following method. EVACUATION AND DEHYDRATION Because the 38AP systems use polyolester oil, which can absorb moisture, it is important to minimize the amount of time that the system interior is left exposed to the atmosphere. Minimizing the exposure time of the oil to the atmosphere will minimize the amount of moisture that needs to be removed during evacuation. Once all of the piping connections are complete, leak test the unit and then pull a deep dehydration vacuum. Connect the vacuum pump to the charging valve in the suction line and to the liquid line service valve. If a unit is installed with the long line check valve assembly, evacuation must be completed on both sides of the check valve to ensure proper evacuation. For best results, it is rec- ommended that a vacuum of at least 500 microns (0.5 mm Hg) be obtained. Afterwards, to ensure that no moisture is present in the system, perform a standing vacuum-rise test. With the unit in deep vacuum (500 microns or less), isolate the vacuum pump from the system. Observe the rate-of-rise of the vacuum in the system. If the vacuum rises by more than 50 mi- crons in a 30-minute time period, then continue the dehydration process. Maintain a vacuum on the system until the standing vacu- um requirement is met. This will ensure a dry system. By following these evacuation and dehydration procedures, the amount of moisture present in the system will be minimized. It is required that liquid line filter driers be installed between the con- denser(s) and the expansion devices to capture any foreign debris and provide additional moisture removal capacity. Be sure to con- sider the pressure drop of the filter drier when determining piping requirements.

CAUTION

For all units with liquid lines of 100 ft (30.5 m) or more or any 025-030 size dual-circuit unit application where evaporator is located higher than the condensing unit and liquid lines exceed 55 ft (16.8 m), a long line option kit must be installed to prevent compressor failure. The long line option kit must be mounted in the liquid line near the condensing unit. See Fig. 21.

CAUTION

The 38AP unit is shipped with a nitrogen holding charge. Use caution when relieving unit pressure to avoid possible equip- ment damage or personal injury.

IMPORTANT: Protect the liquid and suction service valves from the heat of brazing. Schrader valve cores must be removed from the liquid and suction service valves before brazing in field connection piping to avoid damage. Reinsert cores after brazing is completed.

Step 4 Make Electrical Connections

POWER SUPPLY The electrical characteristics of the available power supply must agree with the unit nameplate rating. Supply voltage must be with- in the limits shown in Tables 9-14. See Table 15 for incoming power options.

POWER WIRING All power wiring must comply with applicable local and national codes. Install field-supplied branch circuit fused disconnect per NEC (National Electrical Code, U.S.A) of a type that can be locked OFF or OPEN. Disconnect must be within sight and readi- ly accessible from the unit in compliance with NEC Article 440- 14. General Wiring Notes: 1. The control circuit does NOT require a separate power

source. Control circuit power is obtained by a step-down transformer from the main three-phase power supply. Be sure that the appropriate connection tap is connected on all transformers for the supply voltage.

2. A low-voltage terminal strip (LVT) is provided for field- wired control devices.

NOTE: The field-supplied disconnect should never be off except when unit is being serviced or is to be down for a prolonged peri- od. 3. Power entry is at one end only. 4. All field power enters the unit through a hole located in

the corner post of the unit or the bottom of the control box

WARNING

Before performing service or maintenance operations on unit, turn off main power switch to unit. Electrical shock could cause personal injury.

IMPORTANT: When starting up this equipment for operation, be sure to check tightness of all electrical terminal connections, clamps, screws, etc., as they may have become loose during shipment. It is also advisable to re-tighten all electrical connec- tions after equipment has been in operation and components have reacted to operating temperature.

IMPORTANT: Operating unit on improper supply voltage or with excessive phase imbalance constitutes abuse and may ad- versely affect Carrier warranty.

CAUTION

Proper rotation of condenser fan(s) MUST be verified before compressors are started. Consult the Controls, Start-Up, Oper- ation, Service and Troubleshooting guide provided with the 38AP units for correct procedure. Failure to comply could re- sult in possible equipment damage.

shelf. Refer to Fig. 22 for field power wiring details. Refer to Fig. 6-10 for exact location of field power entry. Be sure to seal entering power wire conduit per NEC require- ments.

5. Terminals for field power supply are suitable only for cop- per conductors. Insulation must be rated 75 C minimum.

6. Units with high short circuit ratings and terminal block option require that specific fuses be applied to achieve this rating. Refer to Tables 13 and 14.

CONTROL POWER Control power is obtained from the main power supply and does NOT require a separate source. A toggle switch (marked Emer- gency On-Off on the unit label diagram and by the switch) allows the control circuit to be manually disconnected when necessary. Crankcase heaters are in an operable state when this switch is in the Off position. All field control wiring must comply with appli- cable local and national codes.

FIELD CONTROL WIRING The standard unit control is microprocessor based, and supports multiple control configurations. See Fig. 23 for MAT/RAT (mixed air temperature/return air temperature sensor) and SAT (supply air temperature sensor) layout. Figures 24-30 show specific control field wiring schemes, depending on unit configuration and desired control requirements. See Controls, Start-Up, Operation, Service, and Troubleshooting guide for specific control method requirements. If the installer is extending sensor cables, plenum-rated, 18 or 20 AWG (American Wire Gage), twisted pair cable should be used. For a space temperature sensor with set point adjustment, use ple- num-rated, 20 AWG, three-conductor, twisted, shielded cable. The standard CCN (Carrier Comfort Network) communication cable is acceptable for this purpose. The wire is suitable for distances of up to 500 ft.

Do not abrade, cut, or nick the outer jacket of the cable. Do not pull or draw cable with a force that may harm the physical or elec- trical properties. Avoid splices in any control wiring. Refer to Controls, Start-Up, Operation, Service, and Troubleshooting guide for additional information. Control options include the following: Variable Air Volume (VAV) (C.TYP = 1) This configuration is the standard VAV option. With this control type, the MBB (Main Base Board) capacity control routine stages compressor capacity to attempt to meet the current Control Point. This option requires a supply air sensor and a mixed air/return air sensor (Part No. 33ZCSENSAT). See Fig. 24. Two-Stage Thermostat, Multi-Step Control (C.TYP=3) This configuration allows the MBB to monitor the thermostat in- puts to make a determination of supply air temperature. Unlike traditional 2-stage thermostat control, the unit is allowed to per- form VAV-style operation using multiple stages of cooling capaci- ty to attempt to meet the current Control Point. This control type also requires a supply air temperature sensor and return air tem- perature sensor (Part No. 33ZCSENSAT), as well as the 2-stage thermostat (Part No. 33CS2PP2S-01). See Fig. 25.

Two-Stage Thermostat (C.TYP = 4) With this constant-volume option, the MBB monitors the thermo- stat inputs to make capacity stage decisions. If Y1 input is closed, no more than 50% of the circuit capacity will be energized. If Y2 is closed, 100% of the circuit capacity will be energized for that circuit and air handler. Y1 closure is not required for 100% capac- ity. This control scheme cannot be used with digital compressors. See Fig. 26. Space Sensor Control (C.TYP=5) This option will allow the MBB to monitor the space temperature sensor and compare it to the Space Temperature Set Point to make a capacity determination. The unit is allowed to use multiple stag- es of cooling control and perform VAV-style operation in an at- tempt to meet the current Control Point. The control requires in- stallation of supply air temperature sensor and mixed air/return air temperature sensor (Part No. 33ZCSENSAT), and one of the fol- lowing space temperature sensors: Space temperature sensor with occupancy override button

(Part No. 33ZCT55SPT) Space temperature sensor with occupancy override button

and set point adjustment slidebar (Part No. 33ZCT56SPT) Space temperature sensor with occupancy override button,

set point adjustment slidebar, and LCD (liquid crystal dis- play) display (Part No. 33ZCT59SPT)

See Fig. 27. Percent Capacity (C.TYP=7) This configuration allows the MBB to monitor the 4 to 20 mA cooling demand signal input to the energy management module and translate this into desired percent capacity for the unit. It is compatible with both standard and digital compressors, and is in- tended for direct capacity control by a third-party control system. An energy management module and 4 to 20 mA generator are re- quired. See Fig. 28. Dual Thermostat (C.TYP=8) This configuration allows for the connection and control of a sin- gle 38APD unit to two separate air handlers. The configuration al- lows the MBB to monitor the thermostat inputs from each of two separate thermostats to make a determination of mode and capaci- ty for each circuit of the 38APD unit. With this control scheme, thermostat T1, Y1 and Y2 contacts operate circuit A. Thermostat T2, Y3 and Y4 contacts operate circuit B. This control option can- not be used with units with digital compressors or 38APS units. It requires an energy management module, two 2-stage thermostats (one for each air handler), and 4 SPST relays for thermostat input. See Fig. 29. Variable Air Volume Setpoint (C.TYP=9) With this configuration, the 38AP unit operates as a VAV unit and controls unit capacity in an attempt to meet a field-supplied 4 to 20 mA supply air temperature request, by staging compressors to at- tempt to meet the current Control Point. A field-supplied 4 to 20 mA signal determines the Active Setpoint. The Control Point is the Active Setpoint adjusted for any temperature reset that is ap- plied. This control type requires the energy management module, a 4 to 20 mA generator, supply air sensor, and mixed air/return air sensor. It is compatible with both standard and digital compres- sors, and is used when variable supply air set points are required and determined by a third-party Building Management System. See Fig. 30.

IMPORTANT: For 208-v systems, the connection tap for all transformers must be changed. The factory default setting is for 230-v. Failure to connect to the proper tap may result in un- reliable operation.

IMPORTANT: Do not run sensor or relay wires in the same conduit or raceway with Class 1 AC service wiring.

* Temperatures calculated with the minimum number of fans operating per circuit. Minimum outdoor-air operating temperature is based on 32C (90F) saturated condensing temperature and 100% capacity.

MISCELLANEOUS ACCESSORIES Energy management module, Navigator display, remote en- hanced display, Touch Pilot display, BACnet1 translator control, LON (local operating network) translator control, and long line accessory kit are available for special applications.

BACnet Communication Option Wiring The BACnet communication option uses the UPC Open control- ler. The controller communicates using BACnet on an MS/TP net- work segment communications at 9600 bps, 19.2 kbps, 38.4 kbps, or 76.8 kbps. Wire the controllers on an MS/TP network segment in a daisy- chain configuration. Wire specifications for the cable are 22 AWG (American Wire Gage) or 24 AWG, low-capacitance, twisted, stranded, shielded copper wire. The maximum length is 2000 ft (609.6 m).

Install a BT485 terminator on the first and last controller on a net- work segment to add bias and prevent signal distortions due to echoing. See Fig. 31-33. To wire the UPC Open controller to the BAS (Building Automa- tion System) network: 1. Pull the screw terminal connector from the controller's

BAS Port. 2. Check the communications wiring for shorts and grounds. 3. Connect the communications wiring to the BAS ports

screw terminals labeled Net +, Net -, and Shield. NOTE: Use the same polarity throughout the network segment. 4. Insert the power screw terminal connector into the UPC

Open controller's power terminals if they are not currently connected.

5. Verify communication with the network by viewing a module status report. To perform a module status report using the BACview keypad/display unit, press and hold the FN key then press the . Key.

To install a BT485 terminator, push the BT485 terminator on to the BT485 connector located near the BACnet connector. NOTE: The BT485 terminator has no polarity associated with it. To order a BT485 terminator, consult Commercial Products i-Vu

Open Control System Master Prices. MS/TP WIRING RECOMMENDATIONS Recommendations are shown in Tables 17 and 18. The wire jacket and UL temperature rating specifications list two acceptable alter- natives. The Halar2 specification has a higher temperature rating and a tougher outer jacket than the SmokeGard3 specification, and it is appropriate for use in applications where the user is concerned about abrasion. The Halar jacket is also less likely to crack in ex- tremely low temperatures. NOTE: Use the specified type of wire and cable for maximum sig- nal integrity.
