27

Installation |

3 If an emergency power-off (disconnect) switch is required by local codes, see the following section, Installing Remote Emergency Power-off (REPO) to install the REPO switch before powering on the UPS.

4 Plug the equipment to be protected into the UPS output receptacles, but do not turn on the protected equipment.

NOTE: Verify that the total equipment ratings do not exceed the UPS capacity to prevent an overload alarm.

Installing Remote Emergency Power-off REPO is used to shut down the UPS from a distance. For example, this feature can be used for shutting down the load and the UPS by thermal relay, in the event of room overtemperature. When REPO is activated, the UPS shuts down the output and all its power converters immediately. The UPS logic power remains on to issue an alarm.

The REPO feature shuts down the protected equipment immediately and does not follow the orderly shutdown procedure initiated by any power management software. Any devices that are operating on battery power are also shut down immediately.

When the REPO switch is reset, the equipment will not return to utility or battery power until the UPS is manually restarted.

The REPO contacts are normally open.

WARNING: The REPO circuit is an IEC 60950 safety extra low voltage (SELV) circuit. This circuit must be separated from any hazardous voltage circuits by reinforced insulation.

CAUTION: The REPO must not be connected to any utility connected circuits. Reinforced insulation to the utility is required. The REPO switch must have a minimum rating of 24 Vdc and 20 mA and be a dedicated latching-type switch not tied into any other circuit. The REPO signal must remain active for at least 250 ms for proper operation.

CAUTION: To ensure the UPS stops supplying power to the load during any mode of operation, the input power must be disconnected from the UPS when the emergency power-off function is activated.

NOTE: For Europe, the emergency switch requirements are detailed in Harmonized document HD-384-48 S1, Electrical Installation of the Buildings, Part 4: Protection for Safety, Chapter 46: Isolation and Switching.

UPS and Battery Care For the best preventive maintenance, keep the area around the UPS clean and dustfree. If the atmosphere is very dusty, clean the outside of the system with a vacuum cleaner. For full battery life, keep the UPS at an ambient temperature of 25C (77F).

NOTE: The batteries in the UPS are rated for a 35 year service life. The length of service life varies, depending on the frequency of usage and ambient temperature. Batteries used beyond expected service life will often have severely reduced runtimes. Replace batteries at least every 5 years to keep units running at peak efficiency.

Transporting the UPS NOTE: The internal UPS batteries MUST be disconnected before transportation.

CAUTION: The following procedure should be performed or supervised by personnel knowledgeable about batteries and the required precautions. Keep unauthorized personnel away from batteries.

If the UPS requires any type of transportation, the batteries must be disconnected (but not removed) before the unit is transported:

1 Verify that the UPS is off and unplugged.

2 Place the UPS on a flat, stable surface with the front of the cabinet facing you.

| Troubleshooting

Troubleshooting The Dell Online Rack UPS is designed for durable, automatic operation and issues alarms to alert you whenever potential operating problems occur. Usually the alarms shown by the control panel do not mean that the output power is affected. Instead, they are preventive alarms intended to alert the user. Active alarms and active notices are accompanied by an audible buzzer.

Accessing Alarms and Conditions The control panel provides troubleshooting information from two main menus:

UPS Status menu: access to all active alarms

Event Log menu: access to the most recent 50 events, which may include active and closed alarms

UPS Status Menu From the UPS Status menu, you can access the following screens for troubleshooting information:

Status summary screen: The status summary screen provides information on both mode and load. When there is a critical alarm, the status summary screen changes from its normal white text on a blue background to dark amber text on an amber background.

Notice or alarm screens: A separate screen appears for each active notice or alarm. If there are no active alarms or notices, the display reads No Active Alarms.

Battery status screen: The battery status screen indicates the battery charge mode, the percent the battery is charged, and the runtime with the present load level.

NOTE: When an alarm is active, the control panel automatically displays an active alarm screen unless the screen lock is enabled by the user.

To access troubleshooting information using the UPS Status menu:

1 Press the button for one second to go to the main menu selection.

2 Press the button to access the UPS Status menu.

3 Press the button to access the UPS status summary screen.
