Powerware 9315s manual Preparing Your Site, Environment Considerations

1.1.2Preparing Your Site

For your Parallel Capacity/Redundant system to operate at peak efficiency, your installation site should meet the environmental parameters outlined in the operator’s manual for the SSBM and UPMs. 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 size and weight requirements shown in the enclosed vendor drawings.

The basic environmental requirements for operation of the Parallel

Capacity/Redundant system are:

Ambient Temperature Range:	0---	25˚C (32---	77˚F)
Recommended Operating Range:	20---	25˚C (68---	77˚F)
Maximum Relative Humidity:	95% noncondensing

The UPM cabinets use forced air cooling to regulate internal component temperature. The SSBM, battery and optional component cabinets use convection 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.

1.1.3Environment Considerations

The life of the Parallel Capacity/Redundant system will be adversely affected if the installation does not meet the following guidelines:

1.The system must be installed on a sealed concrete pad or a sealed concrete floor.

2.The system must be installed in a temperature-controlled indoor area free of conductive contaminants.

1.1.4Preparing for Wiring the Parallel Capacity/Redundant System

NOTE: The external wiring and conduit sizings described in this manual are only provided as a recommended approach. Many design considerations may require an external wiring and conduit configuration much different than the examples provided in this manual. Applicable local codes and national codes must be followed.

Table A in Appendix A covers SSBM and SMB power cabling for a 3∅ / 3W system. Table A is based on the entire 3∅ / 3W system being in a 25_C room ambient and the use of 90_C copper wire. The 500kcmil and 600kcmil cables are used as examples.

Table B in Appendix A covers SSBM and SMB power cabling for a 3∅ / 4W system. Table B is based on the entire 3∅ / 4W system being in a 25_C room ambient, use of 90_C copper wire and a 0.80 derating factor because there are more than three current carrying conductors in a raceway (NEC Table 310 ---16 and Notes). The 500kcmil and 600kcmil cables are used as examples.
