3.5.5 Electrical Installation AC, Method
Electric Shock Hazard: Components with hazardous voltage and energy will electrocute operator. Operator shall
avoid touching live components with hazardous voltage and energy. Verify the absence of voltage using an
appropriately rated multimeter.
Always Wear Proper PPE: The proper Personal Protective Equipment (PPE) must be worn while working in proximity
to hazardous voltage and energy.
Conduit Installation: All conduit connections must be made in such a way as to maintain the NEMA 4X rating of the
enclosure. Failure to maintain the NEMA rating will void the warranty.

Turn AC Switch to OFF: Verify the absence of AC voltage prior to landing any conductors.
Turn the external AC breaker OFF: Verify the absence of AC voltage prior to terminating any conductors.
3.5.5.1 Use the 1-1/2 inch knockouts
Remove the liquid-tight hole plug from the right side or bottom of the AC input portion of the wire-box to install 1-1/2
inch Trade Size conduit and conduit fittings. Then route the cables through the conduit and into the wire-box.
Grounding Conductors: Terminate the grounding conductors prior to terminating the AC cables.
3.5.5.2 Grounding and Bonding
The inverter provides one (1) grounding connection on the AC side and one (1) bonding location. These configurations
are illustrated in Figure 3-22.
A. Grounding via the ground busbar (left) [1]. This is required for grounding the equipment by running the EGC with
the ungrounded conductors.
B. Bonding via the external grounding point (right) [2]. The external bonding connection is provided in case the
inverter/mount needs to be bonded to a metallic structure on which it may be mounted.
