3.05 Battery Cabling - FIG. 1
3.05.1
CAUTION: Assure that hydrogen
gas does not accumulate near the battery by
keeping the area well ventilated. A spark may result
when connecting the final battery wiring due to the
initial charging of the internal input capacitor.
3.05.2 Use stranded copper wire between
the battery and inverter as indicated. UL
requires that a line fuse be installed within 18
inches of the battery. Use only Bussmann ANN
type fuses to 500A and Bussmann ANL for 600A .

3.05.3 NOTE: Using smaller input cable or
longer length will greatly degrade the inverter
peak performance.
IMPORTANT NOTE FOR VE-
HICLE INSTALLATION: Do not use the vehicle
chassis as the negative return in place of a return
cable. Use the same size cable as the positive
connection and run directly to the battery.
3.05.4 Install the wires 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 wiring compartment. A mounting
spark may result when connecting the battery
wire, due to an initial charging of the internal input
capacitor.
3. INSTALLATION
3.01 The following instructions should be thor-
oughly read and understood before installation.
3.02
CAUTION: Inverters produce hazardous
voltages, to avoid risk of harm or fire the unit must
be properly installed.
CAUTION: Damage to the inverter will occur if
correct polarity is not observed when installing the
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 the inverter's 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 conductors.
3.03 Mounting
3.03.1 Locate a suitable, secure vertical or
horizontal mounting surface as close to the battery
as possible without being in the same air tight
compartment. The maximum recommended dis-
tance between the mounting location and the
battery is 20 feet.
CAUTION: If mounting the inverter on a vertical
surface, mount with the front control panel pointing
down.
3.03.2 The location should provide adequate
ventilation and clearance to maintain room tem-
perature during operation. At least 1/2 inch of
clearance is required on all sides.
3.03.3 Secure the unit with 1/4 inch 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.
