Powerware 100160 kVA manual Environmental Considerations, Preparing for Wiring the UPS System

UPS Installation Plan and Unpacking

2.2.1 Environmental Considerations

The life of the UPS system is adversely affected if the installation does not meet the following guidelines:

￿The system must be installed on a level floor suitable for computer or electronic equipment.

￿The system must be installed in a temperature and humidity controlled indoor area free of conductive contaminants.

Failure to follow guidelines may void your warranty.

2.2.2 Preparing for Wiring the UPS System

NOTE If installing, as part of the UPS system, a maintenance bypass without a rectifier input breaker, a minimum of two separate feeds with upstream feeder breakers, or one feed with two upstream feeder breakers, must be provided: one for the UPS and one for the maintenance bypass input. DO NOT use one feed or a single feeder breaker to supply both the UPS and the maintenance bypass.

For external wiring requirements, including the minimum AWG size of external wiring, see Table E through Table G starting on page A-12. The power wiring connections for this equipment are rated at 90°C. If wire is run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be necessary

Control wiring for Emergency Power-off (EPO) and optional accessories (such as building alarms and monitoring interface) should be connected at the customer interface terminal blocks located inside the UPS.

LAN and telephone drops, for use with X-Slot connectivity cards, must be supplied by facility planners or the customer.
