Figure 7 points out the connection areas of the two UPS modules and the parallel
cabinet. The A connection is the power input connections from UPS 1 and UPS 2 to
the parallel cabinet. It is recommended that the UPS modules are labeled in
accordance with Module Output Breaker (MOB) labeling (e.g., the MOB 1 terminals E9
through E11 should be wired with UPS 1 terminals E9 through E11, E12 is the
neutral). The MOBs have already been designated as MOB 1 and MOB 2. See
Table A---2 in Appendix A of this manual for power terminations of the parallel cabinet
and the UPS modules. For power wiring requirements and recommendations, see
Tables A---3 and A---4 in Appendix A of this manual. For power wiring connections or
terminal strip locations, refer to Figure 13 in Appendix A of this manual.
The
B connection is the control wiring connection between the communication panels
of the UPS modules and the parallel cabinet. In the UPS module, the TB3 terminal
strip is located on the left side of the UPS cabinet and to the left of the TB1 terminal
strip on its communication panel. For control wiring requirements and
recommendations, see Table A---1 in Appendix A in this manual. For control wiring
connections and terminal strip locations, refer to Figure 13 in Appendix A of this
manual.
For the UPS Module connections, please refer to the
PowerwareÒ 9315 Installation
manual provided with the UPS system for protection and wiring requirements and
recommendations.
For the
C connections, make sure the bypass feeds originate from the same power
source. Means for separate isolation (circuit breaker or disconnect) are
recommended. Refer to the PowerwareÒ 9315 Installation manual provided with the
UPS system for bypass power wiring.
