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.

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!

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.
