Wiring the Inverter AC Output
WARNING: DO NOT connect the inverter's output to an AC power
source. This could cause severe damage to the inverter and is not
covered under warranty.
The AC Output has three types of AC connections:
• Use the GFCI outlet to power AC loads – This configuration does not
require AC output installation. Plug the AC load into the GFCI outlet.
During By-Pass mode, the AC output is limited by the rating of the
inverter's 20A breaker.
• Hardwire the L2/N2 AC Output terminals (with GFCI Protection) – This
configuration connects the AC loads directly to the output (load side) of
the GFCI outlet. The AC output is limited by the rating of the inverter's
20A breaker and is also connected to the GFCI outlet's "Test" and
"Reset" buttons.
• Hardwire the L1/N1 AC Output terminals – This configuration connects
the AC loads directly to the output side of the internal transfer relay.
The AC output is limited to 30 amps (the rating of the transfer relay
contacts).
If hard-wiring the AC output wires:
1. Route the AC output wires (hot, neutral, and ground) from the AC electrical
sub-panel through the other strain relief clamp on the inverter.
2. Connect the hot (BLACK) wire from the inverter's hot/line (L1 or L2)
output terminal to the sub-panel's main breaker.
3. Connect the neutral (WHITE) from the inverter's neutral (N1 or N2) output
terminal to the sub-panel's neutral busbar.
Wiring the Inverter AC Ground
1. Connect the ground (GREEN) wire from the main panel's ground busbar
and the ground (GREEN) wire from the sub-panel's ground busbar to the
inverter's AC GROUND terminal.
AC Wiring Inspection
1. Verify all wire runs are secured. When installed in a mobile installation,
use wire ties or other non-conductive fasteners to prevent chafing or damage
from movement and vibration.
2. Verify strain reliefs or grommets are in place to prevent damage to the
wiring or conduit where it passes through walls/bulkheads or other openings.
3. After verifying all AC connections are correct, ensure all inverter AC
terminals are torqued correctly.
4. Replace the AC wiring access cover and the covers on the main electrical/
distribution panel.
