8 INSTALLATION
8.1 UNPACKING THE INVERTER
Inspect the shipping container and equipment for loose or damaged parts. If any damage is found,
immediately notify the freight carrier.
8.2 INVERTER INSTALLATION CONSIDERATIONS
The wiring of your inverter installation should conform to the National Electric Code (NEC) and any
other state or local codes in effect at the time of installation. These codes have been written for
your protection and their requirements should be followed.
8.2.1
Mounting
Locate a secure, dry, flat horizontal or vertical surface large enough to mount the inverter. The location
should be as close to the battery as possible without being in the same compartment and should provide
adequate ventilation to maintain room temperature while the inverter is operating. The location must allow
unobstructed cooling airflow at sides and rear of the unit, and the location must be free from road spray,
dripping water or other moisture contamination. A recommended minimum clearance of 2 inches (51 mm)
should be maintained on all sides of the unit.
8.2.2
DC Wiring Considerations
BE AWARE that, as a large number of capacitors become charged upon completion of the DC circuit,
THERE WILL BE A LARGE SPARK when the last battery connection is made. The spark is normal and will
occur every time batteries are connected.
The DC cables should be as short as possible. See Battery Cable Sizing Table for proper size. It is more
electrically efficient to run the lower current AC wiring longer distances.
Route the DC positive and negative cables as close together as possible, and use cable ties to keep them
together. This reduces electromagnetic radiation that could interfere with sensitive electronics.
DO NOT USE THE VEHICLE CHASSIS AS THE DC NEGATIVE CONDUCTOR. Use a cable the same
size as the DC positive to go directly from the inverter to the battery negative (-).
Route the AC and DC power wiring separately and with as much physical separation as possible from low
voltage wiring such as audio and video signal wires.
DC power input cables that pass through steel or other ferrous metal walls need to pass through the same
hole. If two holes are required cut a slot connecting the two holes to prevent a transformer effect.
WARNING:
Do not allow wire fragments or metal shavings to enter the inverter in any way.
8.2.3
DC INPUT WIRING CONNECTIONS
A DC fuse is REQUIRED to protect the inverter and the DC cables.
DC input connectors have been provided to accommodate proper cable hook-up. Good DC connections
and proper wire sizing are critical for the performance and safe operation of the inverter system. The
positive and negative DC inputs have color-coded connectors to protect the “live” connection from any
shorting materials.
Wire sizing charts published in the NEC may allow a greater amp capacity than we require. We have sized
the cable for a minimum voltage drop to maintain better performance of your inverter installation. For best
performance, wire the DC negative directly back to the battery through Battery cables listed in the table
below; do not use the vehicle chassis as the DC negative conductor.
