Environmental Considerations; Preparing For Wiring The Ups System; Inspecting And Unpacking The Ups Cabinet - Eaton Powerware 9390 Installation And Operation Manual

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
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 H starting on page A-11. 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.

2.3 Inspecting and Unpacking the UPS Cabinet

The cabinet is shipped bolted to a wooden pallet and protected with outer protective
packaging material (see Figure 2-1).
