13. Install a redundant signal cable between the For Parallel Use Only and
Standalone/Parallel terminals on each UPS as shown in Figure 62.
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.
14. Remove the Standalone/Parallel terminal block connector from the last UPS
(UPS 3 in Figure 62).
