13. Connect the stripped, soldered (longer) end of the positive (+) cable to the red
stud marked (+) on the inverter and tighten the retaining nut.
14. Connect the stripped, soldered end of the negative (–) cable to the black stud
marked (–) on the inverter and tighten the retaining nut.
15. Connect the other (long) end of the (+) positive cable to one terminal of the heavy-
duty fuse holder.
16. Connect the other conductor of the heavy-duty fuse holder to the (short) positive
(+) battery terminal.
17. Connect the other end of the (–) negative cablewith the ring terminal to the
negative (–) battery terminal.
18. 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.
19. Ensure that all electrical connections have been tightened.
20. Ensure that the inverter’s ON/OFF Switch is in the OFF position.
21. Insert the fuse into the fuse holder. There may be some sparking.
22. Ensure the 12 volt DC power source has an adequate charge.
23. Turn the inverter ON and apply a test load to the 120 volt AC outlets.
* Ring terminals are not included and must be supplied by user.
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).

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!
Operating Tips
For best operating results, the inverter should be placed on a stable, flat surface. The
inverter should only be used in locations that meet the following criteria:
DRY — Do not allow water or other liquids to come into contact with the inverter.
COOL — Surrounding air temperature should be between –0°C and 40°C — ideally
between 15°C and 25°C (60-80°F). Keep the inverter away from direct sunlight,
when possible.
WELL-VENTILATED — Keep the area surrounding the inverter clear to ensure free air
circulation around the unit. Do not place items on or over the inverter during
operation. The unit will shut down if the internal temperature gets too hot.

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.
Vector inverters 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 the “Specifications” section on page 16),
reposition the inverter and fuse holder if necessary.
6. 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. You can
purchase fuses, fuse holders, specific cable or cable battery connectors from your
local electrical supplier or call Vector Technical Support, toll-free, at (866) 584-5504.
Note:
This procedure is 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 6 under “Battery Wiring.” 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. Ensure that mounting hardware does not touch any fuse holder or fuse contacts.
Ensure that fuse is removed from its holder.
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. Sweat-solder end ends 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 terminals* going to the
battery(ies).
11. Connect the short end of the positive (+) cable to a ring terminals* 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 the battery yet.
