Powerware 9330 (10 kVA--40 kVA) Installation and Operation
164201300 Rev . N 013004
The basic environmental requirements for operation of the UPS system are:
Ambient Temperature Range: 0 --- 4 0 ˚C (32---104˚F)
Recommended Operating Range: 20---25˚C (68---77˚F)
Maximum Relative Humidity: 95%, noncondensing
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 rear of
the cabinet. You must allow clearance in front of and behind each cabinet for
proper air circulation. Refer to Drawing 164201300---3 of Appendix A for clearance
requirements.
1.1.3 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 floor suitable for computer or
electronic equipment.
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 A WG size of external
wiring, refer to Tables A through F in Appendix A for the Powerware 9330 (10
kVA---20 kVA) UPS or Tables G through M in Appendix A for the Powerware 9330
(25 kVA---40 kVA) UPS. The power wiring connections for this equipment are rated
at 90˚C. 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 using class 1 wiring methods.
