Installing Distributed Bypass Control Wiring
NOTE
When installing external wiring to the Hot Sync CAN Bridge Card, conduit must be installed to the
UPS cabinet. When installing internal wiring to the 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:
1.
Verify the UPS system is turned off and all power sources are removed. See
Chapter 7, “UPS Operating Instructions,” for shutdown instructions.
2.
Perform the procedure listed in paragraph 5.1.

Terminal block TB3 is accessible on the left side of the X-Slot communication bay
(see Figure 4‐9). To gain access to terminal block TB1, TB2, and the left interface
entry conduit landing plates, remove the screws securing the top internal safety
shield panel and remove the panel. Retain the hardware for later use.
4.
Remove the interface entry conduit landing plates to drill or punch holes (see
Figure 4‐5).
