Preparing Your Site; Environmental Considerations; Preparing For Wiring The Ups System - Powerware 9320 Installation And Operation Manual

1.1.2 Preparing Your Site

For your UPS to operate at peak efficiency, your installation site should meet the
environmental parameters outlined in this manual. If you intend to operate the system at an
altitude higher than 1500 meters (5000 feet), contact your local sales or service office for
important information about high altitude operation. The operating environment must meet
the weight, airflow, size and clearance requirements specified in Appendix A.
The basic environmental requirements of the UPS system are:
Ambient Temperature Range:
Recommended Operating Range:
Maximum Relative Humidity:
The UPS cabinet uses forced air cooling to regulate internal component temperature. Air
inlets are in the bottom sides and front of the cabinet, and outlets in the top of the cabinet.
You must allow clearance in back of the cabinet for proper air circulation. Refer to Table K
of Appendix A for clearance requirements.

1.1.3 Environmental 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 the 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 Tables A and B in Appendix A for the Powerware 9320 (10 kVA or 20 kVA modules) UPS.
The power wiring connections for this equipment are rated using copper wire at 90˚C.
Note that wiring to an external battery cabinet, if used, may be either 75˚C or 90˚C rated.
Control wiring for EPO and optional accessories (such as building alarm and monitoring
interface) should be connected at the customer interface connections inside the front of the
UPS using NEC class 1 wiring methods.
