NOTE When installing external wiring to the Powerware Hot Sync CAN Bridge Card, conduit must be
installed to the UPS cabinet. When installing internal wiring to the Powerware Hot Sync CAN Bridge Card
terminals, route the wiring through the internal opening in the X-Slot communication bay.
NOTE When installing interface wiring for the pull chain, conduit must be installed between UPSs.
To install distributed bypass control wiring:

Chapter 7, "UPS Operating Instructions," for shutdown instructions.
2. Perform the procedure listed in paragraph 5.1.

small top internal safety shield panel and remove the panel. This panel is to the
right of the X-Slot communication bay (see Figure 4‐13 on page 4-19). Retain the
hardware for later use.
