Fuse: 200A 250A 300A
AWG: 4 2 1
3.05.3 NOTE: Using smaller input cable or
longer length will greatly degrade the inverter
peak performance.
IMPORTANT NOTE FOR VEHICLE
INSTALLATION: Do not use the vehicle chassis
as the negative return in place of a return cable.
Use the same size wire as the positive cable and
run directly to the battery.
3.05.4 Install the cables at the battery,
inverter and then fuse holder. Make sure that
good, clean connections are made. Use care not
to touch the positive and negative wires together.
This will result in a violent spark and could result in
exploding batteries and fire.
3.05.5 The battery input terminals are lo-
cated in the inverter wiring compartment. A spark
may result when connecting the battery wire, due
to an initial charging of the internal input capaci-
tor.
3.05.6
CAUTION: Damage to the inverter
will occur if correct polarity is not observed. This
damage is
NOT covered by warranty.
3.06 Remote Switch for Inverter
Operation - Fig. 1
3.06.1 All material used for the remote
switch should be U.L. listed and installed per low
voltage, Class 2, wiring code.
3.06.2 If the “R” option is included, then connect
the cable from the remote panel/status lights with
the mating connector extending from the inverter.
Extension cable is available if necessary.

DC input cables.
CAUTION: Damage to the inverter will occur if an
external AC power source is applied to the inverter’s
AC outlet or its hardwire output.
CAUTION: Be sure both the inverter and the
external AC input circuit breaker or fuse (if needed)
are turned "OFF" during installation.
NOTE: All wiring must follow the National Electric
Code, Provincial, or other codes in effect at the
time of installation, regardless of suggestions in
this manual. All wires should be copper conduc-
tors.
3.03 Mounting
3.03.1 Locate a suitable, secure flat mount-
ing surface as close to the battery as possible
without being in the same air tight compartment.
The maximum recommended distance between
the mounting location and the battery is 20 feet.
3.03.2 The location should have adequate
ventilation and clearance to maintain room tem-
perature while the unit is operating. At least 1/2
inch of clearance is required on all sides.
3.03.3 Secure the unit with #8 or larger
screws or bolts in the mounting slots on the
flanges of the chassis.
3.04 Chassis Bonding Lug - FIG. 1
3.04.1 Connect a #8 gauge or greater cop-
per wire between the bonding lug on the inverter
and the earth grounding system or the vehicle
chassis.
3.05 Battery Wiring - FIG. 1
3.05.1
CAUTION: Make sure that hydrogen
gas does not accumulate near the battery by
keeping the area well ventilated. A spark may
result when connecting the battery wiring due to
an initial charging of the internal input capacitor.
3.05.2 Use stranded copper wire between
the battery and inverter as indicated. A fuse must
be installed between the battery and the inverter.
U.L. requires that the fuse be within 18 inches of
the battery.
