Figure 64. Typical CAN Bridge Card and Redundant Signal Wiring
13. Install a redundant signal cable between the For Parallel Use Only and Standalone/Parallel terminals on
each UPS as shown in Figure 64.
Be sure to check correct polarity when installing the cable.
If polarity or wiring is not correct, the parallel system does not operate normally. For example,
when shutting down one UPS, the remaining UPS transfers the load to bypass instead of
supporting the load. Verify that all wiring is correct for proper operation.
