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
UPS wiring access information, and
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.
10. Secure the wiring to the wire tie anchors provided (see
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.
15. Connect the external parallel CAN wiring to the CAN terminals. See paragraph
