AC Connection Specifications
The AC connections consist of 3 phases (L1, L2, and L3), ground, and neutral. Conductors must be rated for a
minimum of 600 V. Use conductors in accordance with Table 3-1in addition to local electrical codes.

Neutral (Not a current
carrying conductor: Can be
sized equal to or larger than
the EGC)
Equipment Grounding

Electric Shock Hazard
Components with hazardous voltage and energy can electrocute the operator.
Ensure that AC power does not flow into inverter. Verify with a multimeter.
Turn AC Switch OFF before wiring. Wire the AC Connections as shown below. Torque all AC connections
according to Table 3-2 with the 3/16 in (4.75mm) slot torque driver, as shown in Figure 3-14.

When using aluminum conductors it is important to prepare the conductors properly to prevent oxidation. Follow
the steps below to prepare and landing the wires one wire at a time.
a) Remove the oxidation from the connection area of the aluminum conductors.
b) Immediately apply neutral dielectric grease, such as Noalox, and connect the cable to the terminal.
c) If the connection is not made within 30 seconds of applying the grease, repeat this process as an oxidized
layer may have formed on top of the conductor. This oxidized layer is a poorer conductor than the greased
aluminum.
