Environment Considerations; Preparing For Wiring The Ups System - Powerware Uninterruptible Power Supply Installation And Operation Manual

The basic environmental requirements for operation of the UPS system are:
Ambient Temperature Range:
Recommended Operating Range: 20---25˚C (68---77˚F)
Maximum Relative Humidity:
The UPS cabinets use forced air cooling to regulate internal component
temperature. Air inlets are in the front of the cabinet, and outlets are in the top.
You must allow clearance in front of and above each cabinet for proper air
circulation.

Environment Considerations

The life of the UPS system is adversely affected if the installation does not meet the
following guidelines:
1.
The system must be installed on a level, sealed concrete pad or on a sealed
concrete floor.
2.
The system must be installed in a temperature-controlled indoor area free of
conductive contaminants.
Failure to follow guidelines may invalidate UPS warranty.
1.1.4

Preparing for Wiring the UPS System

For external wiring requirements, including the minimum AWG size of external
wiring, refer to Table A or B in Appendix A. 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 EPO and optional accessories (such as building alarms, and monitoring
interface) should be connected at the customer interface panels and terminal
blocks located inside the UPS.
