Remove the liquid-tight hole-plug from the right side or bottom of the AC input portion of the wiring box to install
1-1/2 inch Trade Size conduit and conduit fittings. Then route the cables through the conduit and into the wiring
box.
If the use of smaller conduit is desired, use a proper weather-tight reducing bushing to ensure the Wire Box
maintains its NEMA 4X rating. If larger conduit than 1-1/2 inch is required, either use a reducer or create a larger
concentric hole from the knockout holes provided. However, care must be taken to ensure that water tight seals
can be made with the larger knockouts. No new holes in unspecified areas are allowed or it will impact the NEMA
4X rating and wire box warranty.
Grounding Conductors: Terminate the grounding conductors prior to terminating the AC cables.
The inverter provides one grounding connection on the AC side and one bonding location. These configurations
are illustrated in Figure 3-34.
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.
