5.2 Installing distributed bypass control wiring
NOTE
When installing external wiring to the HotSync CAN Bridge Card terminals, route the wiring
through the internal opening in the X-Slot communication bay.
To install distributed bypass control wiring:
1. Verify the UPS system is turned off and all power sources are disconnected. See Chapter 17: “UPS
operating instructions” for shutdown instructions.
2. Perform the procedure listed in Section 5.1.
3. Terminal block TB3 is accessible on the left side of the X-Slot communication bay (see Figure 4-9
on page 44). To gain access to terminal block TB1, TB2, and the left interface entry conduit landing
plates, loosen the screws securing the top protective cover panel and remove the panel. This panel
is to the right of the X-Slot communication bay (see Figure 4-9 on page 44). Retain the hardware for
later use.
4. Remove the interface entry conduit landing plates to drill or punch holes (see Figure 4-4 on
page 36).
5. Reinstall the interface entry plates and install the conduit.
6. To locate the appropriate terminals and review the wiring and termination requirements, see Section
3.2.3 on page 23, Table 4-1 on page 48, and Figure 4-9 on page 44 through Figure 4-11.
7. Route and install CAN wiring between the UPS cabinets. See Figure 5-2 and Table 5-1 on page 59
for the HotSync CAN Bridge Card terminal location and Figure 5-3, Figure 5-4, and Table 5-2 on
page 58 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 on page 58 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 on page 59 and Table 5-4 on page 60 for wiring information.

authorized Eaton Customer Service Engineer. Contact an Eaton service representative to
schedule a date.
