13. Install a redundant signal cable between the For Parallel Use Only and Standalone/Parallel terminals on
each UPS as shown in Figure 67.
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 67 )
15. Tighten the screws securing each Powerware Hot Sync CAN Bridge Card in its X-Slot communication bay.

or optional X-Slot card ( See section 6.2 Installing Communication Options and Control Terminalsand
section 6.6 Control Terminals . For the communication port, use the supplied serial cable.
