Note: When you connect the cables between the UPS units make sure that you route them through the
grommets in the UPS lower brackets (see Figure 18).

Redundant Signal Cable
a. Install a redundant signal cable between the Standalone/Parallel terminal on the top UPS and the
COM For Parallel Use Only terminal on the bottom UPS (Figure 19).
b. Be sure to check correct polarity when installing the cable.
CAUTION
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.
