2.0 Installation

4. Remove about 50 mm (2”) of the insulating jacket from the AC
cable, and then separate the three wires and strip about 19 mm
(3/4”) of insulation from each wire.

5. Using approved AC wire connectors, connect the outgoing Hot Out,
Neutral Out, and AC Ground wires to the inverter’s AC wires colored
red (HOT OUT), white with black stripe (NEU OUT), and green (AC
GROUND), respectively. Gently pull on the wires to ensure they are
securely held together and check to see that no bare wire is exposed.

6. After making the AC output connections, secure the AC output
cable by tightening the strain relief.

7. Connect the outgoing AC wires to either:

a. an AC load sub-panel equipped with overcurrent protection
(e.g., circuit breakers), or

b. directly to the circuit; when following local standards that permit
using breakers from the main distribution panel or the breakers
on the inverter under certain conditions.

The AC output wiring in the inverter should now be complete. Before
reattaching the AC access cover, review all AC wiring to ensure all
connections are correct and secure.

2.9 Functional Test

After all electrical connections to the inverter, batteries, AC source,
and loads (using a sub-panel) have been completed, follow these
steps to test the installation and the inverter’s operation.

1. Check the battery voltage and polarity before connecting the

batteries to the inverter. Use a multimeter to verify 10 to 14 VDC
at the batteries’ positive and negative terminals.

2. Apply battery power to the inverter by switching the DC

disconnect ON (or close the DC circuit-breaker). The inverter
will remain OFF, but the green status indicator on the front of
the inverter will quickly blink once to indicate that DC power has
been connected and is ready to be turned on.

3. Prior to turning on the inverter make sure all connected loads

(e.g., appliances) are switched OFF, or disconnected from the
AC outlets.

4. a. If a remote switch is connected, press the ON/OFF switch to

turn the inverter on.

b. If no remote switch is connected, lightly press and release
the inverter’s ON/OFF power switch — located on the top of the
inverter — to turn the inverter on.

Verify the inverter’s status indicator is blinking – indicating the
inverter is providing AC power.
