6. The AC Sense Harness is pre-terminated within the AC interface/transformer
assembly and the opposite end is mated with its 9-pin plug to the
corresponding 9-pin jack within the Main Inverter Enclosure.
See Figure 3-17.
7. Replace the access panels on the front of both the main inverter Inductor
Enclosure and the Transformer Enclosure. Additionally, close the front door
to the Main Inverter Enclosure.
To connect the utility service to AC Interface Enclosure:
1. Remove the door clamps and open the door to the AC Interface Enclosure.
2. Route the AC power conductors A, B, C phase, neutral, and a neutral ground
cable through the conduit from the utility service to the AC Interface
Enclosure. See Figure 3-18 for the location of these terminals.
3. Connect the AC power conductors at the S1-2T1 (A phase), S1-4T2
(B phase), and S1-6T3 (C phase) terminals using the M10 hardware. Cables to
these terminals must use a crimp-on type ring terminal or compression-type
lug. Torque these connections to 310 in-lb (35.0 Nm). See Figure 3-18 for the
location of these terminals.
4. Connect the neutral conductor at TB11. Connect the ground conductor at
TB12. Terminations for the neutral and ground conductors within the AC
Interface Enclosure at the TB11 and TB12 locations are made with 3/8-16"
hardware. Cables to these terminals must use a crimp-on type ring terminal or
compression-type lug. The terminal at TB11 should be tightened to a torque
value of 228 in-lb (25.7 Nm). The terminal TB12 should be tightened to a
torque value of 420 in-lb (47.5 Nm). See Figure 3-18 for the location of these
terminals.
5. Close the door to the AC Interface Enclosure and replace the door clamps.
