5. MOUNTING THE INVERTER
Note: Before mounting the inverter system, read the safety
instruction section on page 3.
5.1 Tools for Installation: The following tools are needed for inverter
installation: Crimper, Cable ties, Cutter, Drill, # 2 Phillips Screw driver, Tape measure,
Wire cutters, Wire Strippers.
5.2 Mounting Recommendations:
FIGURE 3: Inverter mounting footprints (dimensions are in inches)
Note: The inverter mounting location should provide adequate
ventilation and clearance to maintain room temperature during
operation. At least 1/2 inch of clearance is required on all sides.
1Locate a suitable, secure vertical or horizontal mounting surface as close to the
batteries as possible without being in the same airtight compartment.
2If mounting the inverter on a vertical surface, it is recommended that the front
control panel be pointing down whenever possible.
3Locate the mounting holes on the chassis flanges and fasten them using ¼ inch
diameter screws to secure the inverter.

6. DC WIRE GAUGE & FUSING
6.1 Inverter Cable: An “inverter cable” kit (positive cable, negative cable and
proper fuse) is needed to connect the inverter to a battery bank. An 8-gauge cable is
also needed to connect the inverter’s bonding lug to ground.
The inverter cable length and the size of the inverter will determine the cable
gauge and the fuse size to use. The maximum inverter cable recommended is 20-ft; it
must be fused within 18-in from the positive (+) terminal of the battery.
Cross reference the inverter model, and the estimated cable length in Table I to
determine proper cable gauge, and fuse size. The inverter cable kit can be purchased
directly from factory. See the accessories section on this manual.
Table I: Cable and Fusing Guide at 5% Voltage Drop at Full Output
Warning: Proper cable gauge must be used to prevent excessive
voltage drop at the inverter DC input.
6.2 Cable Recommendations: To furnish an “inverter cable” kit, follow
below recommendations:
1Use stranded copper cables in all cases.
2Use SGX cross-linked polyurethane insulation type that complies with the high
temperature insulation requirements (125°C.) of SAE J-1127 and vehicle
manufacturer requirements.
3Cable gauge recommendations are minimum. For higher than normal temperature
applications or large motor loads and other applications with high surge currents use
cable gauge 1 to 2 sizes larger than recommended on table I above.
4Keep the cable lengths between battery and inverter as short as possible.
5Use Bussmann fuse type ANN or ANL and fuseblock # 3576. See the accessories
section on this manual.
7. REMOTE “ON/OFF” SWITCH
An optional customer supplied remote “On/Off switch” can be connected to the
remote On/Off switch hookup lead located in the DC field wiring compartment. Use an
18-gauge cable, single pole single throw switch and a 5-Amp in-line fuse installed within
18-in from the positive (+) terminal of the battery.

FIGURE 4: Inverter Cable Assembly and Remote On/Off Switch Assembly Kit
Cable Connection Procedure 1) Remove the in-line fuses from the fuse-holders for cable installation. 2) Connect the inverter’s bonding lug to ground or vehicle chassis. 3) Connect the “inverter cable” set to the appropriate DC input lugs. Tight the strain relief to hold the cables in place. 4) Connect the ring terminated ends of the “inverter cable” set directly to the appropriate battery post. Make sure the battery polarity is observed. 5) Connect the load side of the “remote On/Off” switch to the cable lead extending from the inverter and the fused side to the positive post of the battery. 6) Install the in-line fuses removed in step (1) in the fuse-holders. A typical one time spark will occur when this final connection is made. Plug the flat cable to the back of the remote panel for inverter operation.

10. THEORY OF OPERATION
The “Local On/Off Switch” located on front, or the “Remote On/Off Switch” if
used controls the inverter. Both the Local and “Remote On/Off” switches are configured
in series. To control the inverter remotely set the “Local On/Off switch” to ON.
Inverter Power Mode: The green LED “On” will come on. The AC power produced
by the inverter comes from the energy stored in the battery bank through a
sophisticated electronic inversion process. A transformer, a Metal Oxide Silicon Field
Effect Transistors (MOSFET), a filter capacitor and a 16-bit, 16 MHz microprocessor
control are used to generate clean useful AC power.
Note: The signal output waveform produced by the inverter when in
“inverter mode” is pure sinusoidal. It has a total harmonic distortion of
less than 5%.

1) No AC output power:
1.1) No LEDs on:
•Check in-line fuse which is located within 18” from the battery’s positive post.
•DC connections to be tight and clean.
•Battery voltage to be above 9 VDC.
•Bypass or disconnect remote On/Off switch if used.
1.2) Green LED “Inverter Power” on: Disconnect all loads and connect a test
light to the GFCI output outlet (make sure all breakers are reset)
•If test light is on: Check your AC connections and loads.
•If test light is off: Possible bad GFCI or transfer relay
1.3) Green LED “External Power” on: Repeat 1.2 steps above.
2) Red LED “Low Battery” on: The use of battery isolator is not recommended
due to excessive voltage drop across terminals
•Battery voltage to be above 10.5 when vehicle’s engine is OFF, and above 13
VDC when it is ON.
•Check for proper DC wire gage (see wire gauge & fusing section)
3) Red LED “Overload” on: Unplug all loads, and reset the inverter On/Off:
•If the overload condition persist, possible bad inverter.
•Overload conditions clears, check for short circuits or check load size versus
inverter output wattage size.
4) Red LED “High Temp.” on: Let the inverter to cool down to 40°C (104°F)
