NOTE When installing interface wiring for TB1, TB2, and TB3 connections, the conduit must be
installed between each device and the UPS cabinet.
NOTE Terminal block interface wiring must be installed from the top of the UPS cabinet.
To install wiring to connections:
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, unfasten the front door latch and swing the door open (see Figure 16).
3. Terminal block TB3 is accessible on the right side of the Minislot communication bay. To gain access to
terminal block TB1, TB2, and the left interface entry conduit landing plates, remove the screws securing
the ISBM deadfront panel and remove the panel. Retain the hardware for later use (see Figure 21).
4. Remove the interface entry conduit landing plates to drill or punch holes (see Figure 28).
5. Reinstall the interface entry plates and install the conduit.
Do not directly connect relay contacts to the mains related circuits. Reinforced insulation to the mains is
required.
AVERTISSEMENT!
Ne pas directement brancher les contacts de relais aux circuits du réseau. Une isolation renforcée des réseaux
est nécessaire.
6. To locate the appropriate terminals and review the wiring and termination requirements, see paragraph
3.2.4 UPS System Power Wiring Preparation,Table 15, Table 16, and Figure 21 through Figure 35.
7. Route the wiring through the wire entry in the Minislot panel (see Figure 33)
8. Wire the connectors to the wires to connect the wiring.
9. If wiring TB1 battery interface connections, proceed to paragraph 4.7.2 TB1 Battery Interface Connections;
if wiring the Minislot connections only, proceed to paragraph 4.7.3 Minislot Connections; otherwise,
proceed to Step 10.
10. Reinstall the ISBM deadfront panel and secure with the retained hardware.
