Connecting AC output wires (optional for hardwire AC output)

To make a hardwire connection with the AC OUTPUT of the inverter follow this procedure:
1. Ensure AC and DC power are OFF
2. Install required circuit breaker to the AC load wiring system.
3. Remove the knockout from the sidewall. Do not run the AC input and output wirings through the same knockout.
4. Install the supplied NM clamp (Romex clamp) into the knockout hole
5. Locate the terminal blocks. The whole area will be labeled “AC OUTPUT” and there will be three terminations:
•
(GND), (L), (N)
6. Strip enough of the input cable jacket as to expose the three wires, about 2 inches (50mm).
7. Strip approximately 3/8 inches (10mm) of insulation from each wire. The terminal blocks will accept wire sizes up to
10AWG.
Connecting AC output wires (optional for hardwire AC output)
WARNING
Shock, fire and energy hazard -
Ensure all sources have
been disconnected from power before continuing. Wiring of
the inverter should be in accordance with wiring codes.
WARNING
Shock hazard and equipment damage -
DO NOT connect
any AC input source to the output terminals of the inverter.
Connecting an AC voltage source to the output of the
inverter will cause serious damage, and possibly hazardous
conditions may occur, even if the inverter is OFF.
WARNING
Shock, fire, and energy hazards –
Ensure all other wiring
systems are disconnected and/or disabled before continu-
ing. Wiring of the inverter should be in accordance with
wiring codes. DO NOT connect any AC input source to the
output terminals of the inverter.
IMPORTANT
The Eaton Inverter will not operate if connected to high-
power consumption loads.
The inverter is not meant to operate loads that consume
more than 1000 Watts or 1800 Watts (depending on the
inverter model being used).
The GFCI AC receptacle has been approved by Eaton and
cannot be removed from the inverter. The AC receptacle
must be utilized, unless the AC output is hardwired.
An external GFCI should be used if AC output is hardwired
since the integrated GFCI does not control the AC Output
hardwired connections..
1. Feed the AC input cable into the knockout hole. Facing the front panel of the inverter this should be on the left, and the
label should read “AC INPUT.”
2. Using a small flat blade screwdriver, loosen the terminal screws.
3. Fasten the ground (GND) wire first.
CAUTION
Reverse polarity
– Connecting wires improperly (i.e. the neutral wire into the line termination) will cause the inverter to
break down and possibly cause permanent damage.
4. It is very important to not confuse the connections (i.e. putting the line conductor into the neutral termination). From the
AC cable, typical wire-color schemes are as follows:
•
BARE COPPER or GREEN or GREEN/YELLOW insulation is GROUND wire
•
BLACK insulation is the LINE wire
•
WHITE insulation is the NEUTRAL wire
Confirm proper wires are in correct termination and tighten screws. Leave some wiring slack inside the compartment.

If there is no need to hardwire the AC OUTPUT, make sure the GFCI is in its proper location and install the front panel
back on to the inverter. If hardwiring the AC OUTPUT is required, continue with the procedure below.
