Installing Interface Connections

Use the procedures in the following paragraphs to connect the customer and battery interface connections.

4.7.1

Installing Building Alarm and Relay Contact Connections

To install wiring:

Verify the UPS system is turned off and all power sources are removed. See Chapter 6, “UPS Operating
Instructions,“ for shutdown instructions.

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.

If wiring the interface terminals from the bottom of the UPS, proceed to Step 8; otherwise, proceed to
Step 4.

Top Entry Wiring.

Remove the top interface entry conduit landing plates to drill or punch holes (see

Figure 4-4).

Reinstall the interface entry plates and install the conduit.

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 4-4 for wiring access
information, and Figure 4-9 and Figure 4-10 for UPS interface terminal locations.

Proceed to Step 13.

Bottom Entry Wiring.

Remove the bottom interface entry conduit landing plates to drill or punch holes

(see Figure 4-11).

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 4-11).

11. Route the wiring along the interface wiring channel (see Figure 4-11) to the UPS building alarm and relay

output terminals. See Figure 4-9 and Fi gure 4-10 for UPS interface terminal locations.

12. Secure the wiring to the wire tie anchors provided (see Figure 4-12) using Zip ties.

13. Connect the building alarm interface wiring to the building alarm terminals. See paragraph 3.2.4 and

Table 4-3 for wiring and termination requirements, and Figure 4-13 for terminal assignments.

14. Connect the relay output interface wiring to the relay output terminals. See paragraph 3.2.4 and T able 4-3

for wiring and termination requirements, and Figure 4-14 for terminal assignments.

15. If wiring battery detect and shunt trip connections, proceed to paragraph 4.7.2; if wiring thermal sensor

connections, proceed to paragraph 4.7.3; if wiring generator interface connections, proceed to paragraph
4.7.4; if wiring external parallel CAN connections, proceed to paragraph 4.7.5; 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 16.

16. Close the UPS outside door and secure the latch.

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.
