A. Check all connections and tighten any that may be loose.
B. Ensure that the source battery has adequate charge.
C. If steps A and B do not correct the problem, refer to the “Service Information” section of this Instruction
Manual for assistance.
Permanent Installation (Cables and Fuse Not Supplied)
For permanent installation to heavy-duty battery power you will need:
• Two cables (as indicated in the “Specifications” section of this Instruction Manual)
• Terminals to fit cable ends and stud terminals to inverter
• Hardware and battery connector to connect cables to the battery bank
• A single length of AWG cable multi-stranded, flexible, insulated cable (as indicated in the “Specifications” section
of this Instruction Manual) for chasis ground connection when using inverter in a household application.
• A holder and fuse (see the “Specifications” section of this Instruction Manual)
• Mounting screws, bolts and nuts for mounting the inverter and fuse holder
• A drill for mounting the inverter and fuse holder
• Lead-tin solder, flux, propane torch and an igniter for the torch
• Wire stripper/cutting tool
PRELIMINARY STEPS
The inverter has four slots in its mounting bracket that allow the unit to be fastened against a bulkhead, floor, wall
or other flat surface. Ideally, the mounting surface should be cool to the touch. It is more efficient to use longer AC
wiring than DC wiring, so install the inverter as close as possible to the 12 volt DC power source.
The inverter should be operated in horizontal position; if it is to be mounted on a wall, mount it horizontally so that
indicators, switches, outlets and terminal blocks on the front panel are visible and accessible.
1. If inverter is to be installed in a vehicle, manufacturer recommends that it be shock mounted to either the floor
(in a clear, safe area) or on a secure flat surface.
2. Locate a convenient place to mount the inverter and fuse holder.
3. Perform a test routing of the proposed cable length, but don’t do any cutting at this time (refer to the diagram
in the “Battery Configuration” section of this Instruction Manual).
4. Using an appropriate AWG cable (refer to the “Specifications” section of this Instruction Manual), reposition the
inverter and fuse holder if necessary.
5. After you have performed the above preliminary installation steps, proceed with the actual inverter installation.
Contact the manufacturer for any further installation information or questions.
PERMANENT INSTALLATION PROCEDURE
The cables between the power source and inverter should be set up as illustrated in the diagram in the “Battery
Configuration” section of this Instruction Manual. Unscrew terminal nuts before beginning permanent installation.
Proceed with DC cable and fuse installation as follows:
1. Ensure the inverter’s ON/OFF Power Switch is in the off position.
2. Using tools and hardware, mount the inverter to a flat, stable surface.
3. Ensure that mounting hardware does not touch any fuse holder or fuse contacts. Select an appropriate fuse
(refer to the “Specifications” section of this Instruction Manual) and ensure that the fuse is removed from its
holder.
4. Select appropriate cable (refer to the “Specifications” section of this Instruction Manual). Measure the cable
twice before cutting.
5. Cut one cable length to connect the negative (–) battery terminal to the inverter’s negative terminal, leaving a
little slack in the cable.
6. Cut another cable to connect the positive (+) battery terminal to one side of fuse holder, leaving a little slack.
7. Cut the final cable to connect the other side of fuse holder to the inverter’s positive (+) terminal.
8. Strip the end insulation of all three cables to 1-inch (2.45 cm).
9. Sweat-solder end of all cables. For safety, do this in an open space because it may require the use of a propane
torch.
10. Connect one end of the negative (–) cable to a ring terminal* going to the battery(ies).
11. Connect the short end of the positive (+) cable to a ring terminal* going to the battery(ies).
12. Crimp or clamp ring terminals of the negative (–) and positive (+) cables (going to the battery), but do not
connect to the battery yet.
