NOTE 1 If installing interface wiring connections between standalone cabinets, conduit must be
installed between each cabinet.
NOTE 2 Disconnect terminal block plugs from terminal blocks to wire plugs.
To install 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. If not already opened, open the front door by lifting the latch from the bottom and turning to the right
(counterclockwise) and swing the door open.
3. If wiring the external parallel CAN connections using the inter-cabinet wiring access pass-through (line-up-
and-match configurations), proceed to Step 4; if wiring the external parallel CAN connections using bottom
entry access, proceed to Step 6; if wiring the external parallel CAN connections using top entry access,
proceed to Step 12.
4. Pass-through Wiring. Route the external parallel CAN control wiring between UPS cabinets through the
top UPS inter-cabinet wiring access pass-through to the UPS external parallel terminals. See Figure 19 for
UPS wiring access information, and Figure 22 and Figure 23 for UPS interface terminal locations.
5. Proceed to Step 15.
6. Bottom Entry Wiring. Remove the bottom interface entry conduit landing plate to drill or punch holes
(see Figure 24).
7. Reinstall the interface entry plate and install the conduit.
8. Route the external parallel CAN control wiring through the bottom interface entry conduit landing plate to
the bottom access interface wiring channel along the inside of the front door.
9. Route the wiring along the interface wiring channel to the UPS external parallel terminals. See Figure 22
and Figure 23 for UPS interface terminal locations.
10. Secure the wiring to the wire tie anchors provided (see Figure 25) using Zip ties.
11. Proceed to Step 15.
12. Top Entry Wiring. Remove the top interface entry conduit landing plate to drill or punch holes (see
Figure 17).
13. Reinstall the interface entry plate and install the conduit.
14. Route the external parallel CAN control wiring through the top interface entry conduit landing plate to the
UPS external parallel terminals. See Figure 22 and Figure 23 for UPS interface terminal locations.
