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.
Use conductors with a temperature rating of at minimum 90°C. 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.
Before wiring, mark locations of conduit entry on the removable gland plate (located on the bottom of the
inverter). Remove the gland plate before drilling or punching holes to prevent metal debris from entering the
inverter enclosure. Re-attach the gland plate to install conduit fittings and conduit. 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 Type 4X rating. Conduit holes or other modifications to the enclosure
are not permitted anywhere on the enclosure except for the removable conduit panel.
3.3.1
Remove Cover on Wiring Box
Use a #3 Phillips-head screwdriver to remove the 10 screws from the cover of the Wiring Box, as shown in Figure
3-6.
Figure 3-6 Wiring Box Cover Screws (Quantity 10)
When replacing the cover, all 10 screws must be installed to maintain the enclosure rating.
This prevents water from entering the enclosure that could potentially damage the
equipment. Damage due to water is not covered under warranty.
