Vector Power On Board VEC031POB Owner's Manual & Warranty Information page 7

CAUTION: Reverse polarity connection will result in a blown fuse and
may cause permanent damage to the inverter.
Connecting to a Power Source Using Provided Cables:
If the inverter is to be used for extended periods at power levels above
150 watts, direct connection to the power source is recommended. Use
the provided cables to connect the Power-On-Board™ 400 directly to
the 12 volt power source using the following guidelines:
1. Check to be sure the Power-On-Board™ 400 power switch is turned
off and that no flammable fumes are present.
2. Connect the black cable to the black post marked "(-)" on the back of
the inverter. Connect the battery clip to the negative terminal of the
battery.
3. Connect the red cable to the red post marked "(+)" on the back of the
inverter. Connect the battery clip to the positive terminal of the battery.
4. Check to be sure that all connections between battery clips and
terminals are secure.
Direct Hardwiring to Power Source:
Use #10 AWG wire if the inverter to power source connection is 10 feet
or less. For longer cable lengths use #8 AWG wire. In either case, pro-
tect the positive (+) wire from shorts by installing a 40 Amp fuse or
circuit breaker close to the DC power source (battery) terminal.
1. Check to be sure the inverter's power switch is turned off and that
no flammable fumes are present.
2. Identify the positive (+) and negative (-) DC power source (battery)
terminals.
3. Install a fuse holder or breaker close to the positive (+) terminal of the
DC source (battery).
4. Connect a length of wire on one side of the fuse holder or circuit
breaker. Connect the other end if the wire to the Positive (+) terminal
of the inverter.
5. Connect a length of wire between he inverter's negative (-) terminal
and the DC power source negative (-) terminal.
6. Connect a short length of wire to the other terminal of the fuse holder
or circuit breaker. Mark it "POSITIVE" or "+".
7. Connect the free end of the fuse or breaker wire to the positive
terminal of the DC power source (battery).
