14. Remove the Standalone/Parallel terminal block connector from the last UPS (UPS 3 in Figure 64).
15. Tighten the screws securing each Powerware Hot Sync CAN Bridge Card in its X-Slot communication bay.
16. If you are installing power management software, connect your computer to the UPS communication port
or optional X-Slot card (see "Installing Communication Options and Control Terminals" on page 108). For
the communication port, use the supplied serial cable.
NOTE Installing one Eaton Power Xpert UPS Gateway card allows you to communicate
with all UPS modules connected to the same parallel bus configuration.
17 . If you left the UPSs unattached to the rack, secure the front and rear of each UPS as described in Step 14
and Step 15 on page 68.
18. If your rack has conductors for grounding or bonding of ungrounded metal parts, connect the ground cable
(not included) to the ground bonding screw. See Figure 60 on page 74 for the location of the ground
bonding screw.
19. You can install an optional REPO circuit that will shut down the entire parallel system using a single
switch. See "Remote Emergency Power-off" on page 112 to install the REPO switch before powering on
the parallel system.
20. Connect the parallel input cord from each paralleled UPS, as shown in Figure 65:
Loosen the two screws on the plug retainer and slide the plug retainer out.
l
Gently loop and twist the parallel input cord as shown to minimize stress on the cord. The loop and
l
twist for each cord may vary depending on configuration and strain relief to the BladeUPS Bar in the
rack.
Insert the parallel input cord into the socket. The plug is fully seated when the plug latches snap (top
l
and bottom) into place.
NOTE Make sure the connectors are snapped in tightly to prevent incorrect system
operation.
Slide the plug retainer back in and tighten the screws.
l
NOTE The plug retainer prevents the plug from being inadvertently unplugged.
