5.3 Installing Distributed Bypass Control Wiring
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.
3. Terminal block TB3 is accessible on the left side of the X-Slot communication bay (see Figure 4-24). 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 4-19).
5. Reinstall the interface entry plates and install the conduit.
6. To locate the appropriate terminals and review the wiring and termination requirements, see
paragraph 3.2.4, Table 4-1, and Figure 4-24 through Figure 4-27.

Hot Sync CAN Bridge Card terminal location and Figure 5-3, Figure 5-4, and Table 5-2 for wiring
information.
8. If a tie cabinet with Module Output Breakers (MOBs) is being wired, proceed to Step 11; otherwise,
proceed to Step 9.
9. Route and install distributed bypass system pull-chain wiring between the UPS cabinets. See Figure 5-5
and Table 5-3 for wiring information.
10. Proceed to Step 12.
11. Route and install distributed bypass system pull-chain wiring between the UPS cabinets and tie cabinet
MOBs. See Figure 5-6 and Table 5-4 for wiring information.
12. Reinstall the top internal safety shield panel and secure with the retained hardware.

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.
NOTE Setup of the Powerware Hot Sync CAN Bridge Card for parallel operation must be
performed by an authorized Eaton Customer Service Engineer. Contact an Eaton
service representative to schedule a date.
