Wiring
Turn the AC Switch to OFF before wiring. The AC switch is located on the right side of the inverter (Figure 2-3.)
Turn AC Switch to OFF
Verify the absence of AC voltage.
Terminations are rated for both 75°C and 90°C rated conductors. Ensure that all connections are in compliance
with NEC ANSI/NFPA 70 and local electrical codes. With longer wire runs, larger conductors than required by
Code are often used to reduce the voltage drop. See Section 3.5 for AC connection specifications and Section
3.8.1 for DC connection specifications.
Keep AC and DC connections in separate conduit. All conduit used for connections must use rain tight or wet
location connectors that comply with UL 514B to maintain the enclosure’s NEMA 4X, Type 3R, IEC IP66 rating.
Conduit holes or other modifications to the enclosure are not permitted anywhere on the enclosure except for
the designated conduit entry area.

turn latches on the front cover, as shown in Figure 3-6. Lift the bottom of the cover and swing upward. Make
sure both cover supports are engaged, as in Figure 3-7.
