INSTALLATION
4.1
Unpacking the Inverter
Inspect the shipping container and equipment for loose or damaged parts. If any damage is found,
immediately notify the freight carrier.
4.2
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.
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 air flow at sides and bottom 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.
4.3
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.
1. The DC cables should be as short as possible. It is more electrically efficient to run the lower
current AC wiring longer distances (see battery cable sizing table for proper size)
2. 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.
3. 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 (-).
4. 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.
5. DC power input cables which 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 fall into the inverter in any way.
DC INPUT WIRING CONNECTIONS
A DC fuse is REQUIRED to properly protect the inverter.
DC input studs have been provided to accommodate crimp lugs, with 5/16” hole, with battery cable up to 4/0
AWG, see table below. 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 covers to protect
the “live” connection from any shorting materials.
