Failure to connect the chassis bonding lug to the chassis of the vehicle, the installation's grounding system,
or to earth ground may result in a lethal shock hazard.
AC Wiring Procedure (refer to Figure 3-1)
Warning:
Make certain that the AC field wiring (upper right of the wiring compartment) and the Signal wiring
(at the lower right of the wiring compartment) are kept separate to avoid any problems or conflicts with
code. Make certain to route the Signal wires out of the provided port (lower most on the right side of
the unit). This is to insure that there are no problems that may arise from the poor insulation
properties of most signal level wire. Make certain that the auxiliary contact and option wiring are
routed below the barrier, and the AC Power Wires above the barrier.
Step 1: Connect the AC output. Remove the front cover to expose the AC input and output terminal strips.
I
dentify the right terminals labeled “AC Output”. Insert the output field wires through the nearest (to the
board) strain relief into the AC wiring compartment. Tighten the strain relief. Connect the copper field
wires to the proper AC output terminals and tighten to 9 lb-in max.
Warning:
Do not attempt to use a stranded wire. Stranded wire has a tendency to break off some of the
strands and will drop into the unit causing possible failures. If a stranded wire is used, the appropriate
“ring terminal” must be used.
Step 2:
Connect AC Input. Identify the terminal strip’s terminals labeled “AC Input”. Insert the field wires
through the (closest to the front panel) strain relief into the AC wiring compartment. Tighten the strain
relief. Connect the copper field wires to the proper AC input terminals and tighten to 9 lb-in max.
Replace the front cover.
Warning:
Do not attempt to use a stranded wire. Stranded wire has a tendency to break off some of the
strands and will drop into the inverter causing possible failures. If a stranded wire is used, the
appropriate “ring terminal” must be used.
Step 3: Connect Bonding Lug. Use a 8 AWG or larger copper conductor to connect the chassis bonding lug to
the chassis of the vehicle, the installation’s grounding system, or to earth ground.
Step 4: Verify Installation. Verify all connections are tight and secure for maximum performance.
System Start-up and Testing
Step 1:
Completely install the ITC-Series Inverter/Charger following the system design considerations and
instructions provided previously in this manual.
Step 2:
Place the System Power On/Off switch located on the front of the inverter in the OFF position.
Step 3:
Verify that the external GFCI breaker is reset and connect an AC load, such as a 100-Watt light. Note:
some GFCI’s require power to be applied before they will reset.
Step 4:
Turn ON the battery DC power to the inverter.
Step 5:
Turn ON the AC shore power (or generator) to supply the AC input power to the system
Step 6:
Place the System On/Off Power switch located on the front of the inverter to the ON position.
Step 7:
The Lights on the Control/Display Unit on the front of the inverter should come ON, by doing a lamp
test.
Step 8:
Disable the Charger Operation of the unit by pressing the Charger ON/OFF button once if the Charger
LIGHT is On or blinking. This turns the charger function OFF.
Step 9
If the Inverter LIGHT is not On or blinking, enable the Inverter Operation of the unit by pressing the
Inverter ON/OFF button once. This turns the Inverter function ON.
Step 10 The AC output test light should come ON, indicating the presence of shore power and correct
operation of the AC transfer switch.
