Powerware 9315s Installing UPM Cabinets, Installing Ssbm Wiring, Setting the Power+ Trip Unit

2.5.2Setting the Power+ Trip Unit

As received, the long-time delay, long-time pickup, and instantaneous trip settings are at their maximum values. It is the user’s responsibility to install the long-time delay, long-time pickup, and instantaneous trip settings which are in compliance with their overall coordination study.

Using GE Document DEH---049,User’s Guide for the Power+t Trip Unit, set the required long-time delay, long-time pickup, and instantaneous trip settings on all SSBM and SMB circuit breakers trip units.

NOTE: The applicable time ---current curve is GE Document GES ---9890E.

2.6Installing UPM Cabinets

To install the UPMs, refer to the Powerware 9315 UPS Insatallation manual provided with the UPMs.

2.7Installing SSBM Wiring

NOTE: Refer to section 1.1.4 for additional guidance for wiring and conduit placement.

NOTE: For SSBM with100 kAIC short circuit rating, power rating must be secured as shown in drawing 164201373 ---1.

1.Install input power wiring to the SSBM and power wiring between the UPMs, SSBM, and critical load. Each UPM is individually wired to the SSBM UPM input bus. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information.

2.Install control wiring between UPMs and the SSBM. PowerNet network is wired serially (daisy-chained) between UPMs and SSBM. Wire dual redundant PowerNet in separate conduits for maximum failure protection. Refer to Appendix A of this manual for wiring and termination requirements and wiring access information.

3.If a common UPM battery is being used, a separate DC source disconnect device must be provided for each UPM. Wire shunt/UV DC disconnect trip and battery breaker open signals from each UPM to the respective DC source disconnect.

4.After wiring the Parallel Capacity/Redundant system to the facility power and critical load(s), be sure to ground the system according to local and/or national electrical wiring codes, using your own cabling and conduit.

5.Install batteries in accordance with all applicable codes and regulations, including the National Electrical Code (NEC), Article 480.
