4.5 Electrical Connections

Proceed with making the electrical connections of the inverter once it has been properly

secured to the concrete slab. Terminal connections for the inverter are located inside the

unit. When facing the inverter:

• DC terminals are located on the left side

• AC terminals are on the right side

The AC and DC busbars accept standard terminal lug-crimped wires mounted to the

busbar ttings with standard 3/8” mounting hardware.

For the optional fused subcombiners, the wire is inserted directly into the fuse holder

assembly. Accepted cables sizes for each subcombiner lug option are shown in Table D-4

Appendix D - Limits, Fault Codes, Torque Values, and Wire Sizes

The inverter is a NEMA 4 enclosure. Use only rain-tight or wet-location conduit hubs

and install these hubs as shown in the following gure.
