NOTE 1 If installing interface wiring connections between standalone cabinets or separate
devices, conduit must be installed between each cabinet or device.
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 interface terminals from the bottom of the UPS, proceed to Step 8; otherwise, proceed to
Step 4.
4. Top Entry Wiring. Remove the top interface entry conduit landing plates to drill or punch holes (see
Figure 15).
5. Reinstall the interface entry plates and install the conduit.
6. Route the UPS building alarm and relay output interface wiring through the top interface entry conduit
landing plates to the UPS building alarm and relay output terminals. See Figure 15 for wiring access
information, and Figure 20 and Figure 21 for UPS interface terminal locations.
7. Proceed to Step 13.
8. Bottom Entry Wiring. Remove the bottom interface entry conduit landing plates to drill or punch holes
(see Figure 22).
9. Reinstall the interface entry plates and install the conduit.
10. Route the UPS building alarm and relay output interface wiring through the bottom interface entry conduit
landing plates to the bottom access interface wiring channel along the inside of the front door (see
Figure 22).
11. Route the wiring along the interface wiring channel (see Figure 22) to the UPS building alarm and relay
output terminals. See Figure 20 and Figure 21 for UPS interface terminal locations.
12. Secure the wiring to the wire tie anchors provided (see Figure 23) using Zip ties.
13. Connect the building alarm interface wiring to the building alarm terminals. See paragraph
3.2.3 UPS System Interface Wiring Preparation and Table 12 for wiring and termination requirements, and
Figure 24 for terminal assignments.
14. Connect the relay output interface wiring to the relay output terminals. See paragraph
3.2.3 UPS System Interface Wiring Preparation and Table 12 for wiring and termination requirements, and
Figure 25 for terminal assignments.
15. If wiring battery detect and shunt trip connections, proceed to paragraph
4.7.2 Installing Battery Detect and Shunt Trip Interface Connections; if wiring generator interface
connections, proceed to paragraph 4.7.4 Generator Interface Connections; if wiring Minislot connections,
proceed to paragraph 4.7.5 Installing Minislot Interface Connections; otherwise, proceed to Step 16.
