Installing External Parallel CAN Control Wiring and Connections
NOTE 1
NOTE 2
To install wiring:
1.
Verify the UPS system is turned off and all power sources are removed. See Chapter 6, "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 4-6 for
UPS wiring access information, and Figure 4-9 and Figure 4-10 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 4-11).
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 (see Figure 4-11).
9.
Route the wiring along the interface wiring channel (see Figure 4-11) to the UPS external parallel terminals.
See Figure 4-9 and Figure 4-10 for UPS interface terminal locations.
10. Secure the wiring to the wire tie anchors provided (see Figure 4-12) 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 4-4).
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 4-4 for wiring access information and Figure 4-9 and
Figure 4-10 for UPS interface terminal locations.
15. Connect the external parallel CAN wiring to the CAN terminals. See paragraph 3.2.4, Table 4-5, and
Table 4-6 for wiring and termination requirements, and Figure 4-21 and Figure 4-22 for wiring information
and terminal assignments.
16. If wiring external parallel pull chain connections, proceed to paragraph 4.7 .6; if wiring Minislot connections,
proceed to paragraph 4.7 .7; if wiring REPO connections, proceed to paragraph 4.8; otherwise, proceed to
Step 17.
17 . Close the UPS outside door and secure the latch.
