Caution

Input signal wire shall not be bound together with or placed close to the main circuit and power line. Keep 300 mm or longer distance between them. The noise causes malfunctions. For wiring voltage circuit and ZCT secondary, use separate cables from other external signals in order to prevent from AC surge and induction. In case of measuring leakage current for resistance, it is possible on single-phase 2-wire, single-phase 3-wire, three-phase 3-wire delta circuit. The measurement of two circuits is possible at one module in the same system in the same trans. ZCT CZ series and ZT series do not have a secondary output polarity. Length of wire between ZCT and this module is max. 50 m. ZCT output wire from Z+ and Z terminal has to be stranded at 40 times/m. Wiring it is necessary to wire voltage input. When 220 V or higher is loaded to the voltage circuit, use a voltage transformer. For connection to P1 - P3 terminals on QE82LG, connect the secondary of transformer. Make sure that terminal symbols are correct. If phase wires are connected incorrectly, accurate measurement cannot be performed. For the actual usage, connect the FG terminal to ground. (D-type ground: Type 3) Connect it directly to the ground terminal. Do not connect to FG terminal during the insulation resistance test and pressure test.

6.2 How to connect wires Use appropriate electric wires as described below. Stripping length of the used wire in use has to be 10 to 11mm. Check the stripping length using the strip gauge of QE82LG module. When stranded wire is used, a bar terminal must be used. When attaching and detaching cables to/from the terminal, use the

push button. Check that the wire is securely inserted. Insert a wire to the terminal all the way until it touches the end. Applicable wire(Usable electric wire)

Single wire: 0.5 1.2mm AWG24AWG17 Stranded wire: 0.5 1.3 mm AWG20AWG16

UL/c-UL listed corresponds, use the wires according to the following conditions. Single wire : AWG24AWG18 Stranded wire : AWG20AWG18 60/75 copper conductor only.

COMPLIANCE WITH THE EMC AND LOW VOLTAGE DIRECTIVES (1) For programmable controller system

To configure a system meeting the requirements of the EMC and Low Voltage Directives when incorporating the Mitsubishi programmable controller (EMC and Low Voltage Directives compliant) into other machinery or equipment, refer to Chapter 9 "EMC AND LOW VOLTAGE DIRECTIVES" of the QCPU User's Manual (Hardware Design, Maintenance and Inspection). The CE mark, indicating compliance with the EMC and Low Voltage Directives, is printed on the rating plate of the programmable controller.

(2) For this module For the compliance of this module with the EMC and Low Voltage Directives, refer to Section 6.1 Wiring.

1. Features This enables to measure leak current for safety actions.

By monitoring leak current (Io), risk for electric shock can be detected. This enables constant monitoring of insulation for equipment.

By monitoring leak current for resistance (Ior), deterioration of equipment insulation can be tracked. This enables 2-level alarm monitoring during monitoring for each measuring element.

For each leak current (Io) and leak current for resistance (Ior), 2-level alarm monitoring can be performed without a sequence.

This enables to measure two circuits, using one device. At the power source with the same-phase wire method, a single device can measure two circuits.

This enables to measure sensitive. By changing setting to high sensitivity mode, this enables to measure from 0.01mA. 2. Checking packaged contents

The following items are included in the package. Check that no items are missing. Insulation Monitoring Module x 1 Users Manual (Hardware) x 1

3. Safety Precautions

Danger For installation and wiring works, make sure that the power source is shut off for all outside phases. If all phases are not turned off, it may cause an electric shock or product damages.

Programmable Controller

Caution

Any person who is involved in the installation and the wiring of this Sequencer should be fully competent to do the work.

Use the programmable controller in an environment that meets the general specifications in the Users Manual for the CPU module used. Failure to do so may result in electric shock, fire, malfunction, or damage to or deterioration of the product.

To mount the module, while pressing the module-mounting lever located in the lower part of the module, fully insert the module fixing projection(s) into the hole(s) in the base unit and press the module until it snaps into place. Incorrect mounting may cause malfunction, failure or drop of the module. When using the Sequencer in an environment of frequent vibrations, fix the module with a screw.

Tighten the screw within the specified torque range. Under tightening can cause drop of the screw, short circuit or malfunction. Over tightening can damage the screw and/or module, resulting in drop, short circuit, or malfunction.

Shut off the external power supply for the system in all phases before mounting or removing the module. Failure to do so may result in damage to the product.

Do not directly touch any conductive part of the module. Doing so can cause malfunction or failure of the module.

FG terminal must be grounded according to the D-type ground (Type 3) dedicated for sequencer. Failure to do so may result in an electric shock or a malfunction.

When using this product, make sure to use it in combination with zero phase transformer (CZ series and ZT series). Please not to exceed the ratings of this product for input of zero phase transformer. For further details, please refer to zero phase transformer manual to maintain the functionality and the accuracy of this product.

This module and the zero-phase current transformer are used for less than 600V circuit only. They are not used with exceeding 600V circuit.

ZCT CZ series and ZT series do not have a secondary output polarity. Take care not entering any foreign objects such as ships and wire pieces into the module. It may cause a fire, a failure or a malfunction.

In order to prevent the module from incoming foreign objects such as wire pieces during wiring work, a foreign-object preventive label is placed on the module. While a wiring work is performed, keep the label on the module. Before operating the system, peel off the label for heat release. If the foreign-object preventive label is not peeled and the system is in use, residual heat inside the module may reduce the product life.

The wires to be connected to the module shall be placed in a duct or fixed together by clamping. If the electric wires are not placed in the duct or clamped together, loosen wires or their movement or careless stretch may cause a breakage of the module or wire or a malfunction due to poor contact of electric wires.

Use appropriate size of electric wires. If inappropriate size of electric wire is used, it may cause a fire due to generated heat.

In case using stranded wire, take measures so that the filament should not vary by using a bar terminal or by processing the point twisted. Use the bar terminal appropriated for the size of electric wires. If inappropriate bar terminal is used, a wire breakage or a contact failure may occur, which may cause a device malfunction, a failure, a burnout, or a fire.

After inserting the electric wire or a bar terminal, make sure that no missing insertion is existing. Missing insertion may cause a device malfunction, a fire, or an electric shock.

If the wires connected to the module are strongly pulled off, it may cause a malfunction or a breakage to the module or the wire.

Ensure the wiring to the module properly, checking the rated voltage and current of the product and the terminal pin assignment. If the input voltage exceed the rated voltage or the wiring is improper, it may cause a fire or a breakage. (Tensile load: 22N or less)

Do not exceed the specified voltage when doing an insulation resistance test and a commercial frequency withstand voltage test.

3.1 Precautions for Operating Environment and Conditions Do not use this product in the places listed below. Failure to follow the instruction may cause malfunctions and a life decrease of product.

Places the Ambient temperature exceeds the range 0 55C. Places the Relative humidity exceeds the range 5 95% or places with dewfall. Altitude exceeds 2000 m. Places exposed to rain or water drop.
