4. Measure the cable twice before cutting the cable.
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. Crimp or sweat-solder the copper strands to ring terminals. For safety, do this in
an open space because it may require the use of a propane torch.
10. Crimp or clamp on a heavy-duty, battery connection terminal to the other end of
the NEGATIVE (–) and POSITIVE (+) cable. Connect the NEGATIVE (–) battery
terminal cable to the NEGATIVE (–) battery terminal connector.
11. Connect the ring terminal end of the NEGATIVE (–) cable into the black stud
marked (–) on the inverter back panel and tighten the retaining nut.
12. Connect the battery connector to the NEGATIVE (–) battery terminal.
13. Connect the ring terminal end of the POSITIVE (+) cable into the red stud marked
(+) on the inverter back panel and tighten the retaining nut.
14. Connect the otehr end of the POSITIVE (+) cable to one terminal of hte heavy-duty
fuse holder.
15. Connect the other conductor of the heavy-duty fuse holder to the POSITIVE (+)
battery terminal.
16. Connect an insulated wire (at least #12 AWG) between the chassis grounding
screw on the inverter’s case and a solid electrical ground to minimize possible
electrical noise in TVs and radios.
Do not connect this wire to the
negative DC input terminal.
17. Ensure that all electrical connections have been tightened.
18. Insert the fuse into the fuse holder. There may be some sparking.
19. Ensure the 12 volt DC power source has an adequate charge.
21. Turn the inverter ON and apply a test load to the 120 volt AC outlets.
If, after following all of the above steps, the inverter does not perform properly, the
source voltage may be too low or the cables may be too long (or the gauge too light).
Having checked and, if necessary, corrected these conditions, contact Vector Technical
Support, toll-free, at (866) 584-5504 for assistance if problems persist.
Connection To Load
The Power Inverter is equipped with standard North American three-prong type
outlets. Plug the cord from the equipment you wish to operate into the AC outlet(s).
Make sure the combined load requirement of your equipment does not exceed
maximum continuous power.
The Power Inverter is engineered to be connected directly to standard electrical and
electronic equipment in the manner described above. Do not connect the Power
Inverter to household or RV AC distribution wiring. Do not connect the Power Inverter
to any AC load circuit in which the neutral conductor is connected to ground (earth)
or to the NEGATIVE of the DC (battery) source.
WARNING
Do not connect to AC distribution wiring!

Permanent Installation
For permanent installation to heavy-duty battery power you will need:
• Two cables (as indicated in the “Specifications” section on page 16)
• 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 on page 16) for chasis ground connection
• A holder and fuse (see “Specifications” on page16)
• 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, it is recommended that the unit 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 on page 8 under “Battery Configuration”).
4. Be sure that the POSITIVE (+) and NEGATIVE (–) cables to the battery do not
exceed six feet.
5. Using an appropriate AWG cable (see “Specifications” on page 16), reposition
the inverter and fuse holder if necessary.
6. Proceed with the actual inverter installation.
You can purchase fuses, fuse holders, specific cable or cable battery
connectors from your local electrical supplier. These are not supplied
with this unit. Contact the manufacturer for any further installation
information or questions, toll-free, at (866) 584-5504.
Note:
The following procedures are for using locally purchased supplies. If a Vector
Cable Set is used, follow the directions included with that set.
PERMANENT INSTALLATION PROCEDURE
The cables between the power source and inverter should be set up as illustrated in
the diagram on page 8. Also refer to the “Control and Function Guide” on page 2.
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 surface.
3. Mount the fuse holder to its mounting surface using appropriate hardware. Ensure
that mounting hardware does not touch any fuse holder or fuse contacts. Ensure
that fuse is removed from its holder.
