4. INSTALLATION
4.1 POWER SOURCE REQUIREMENTS
The power source must provide 12.5 volts DC and must be able to supply the necessary
current to operate the load. The power source may be a battery or a well-regulated DC
power supply. To obtain a rough estimate of the current (in amperes) the power source must
deliver, simply divide the power consumption of the load (in watts AC) by 10.
Example: If a load is rated at 750 watts AC, the power source must be able to deliver: 750
divided by 10 = 75 amperes
CAUTION: The Vector Power Inverter must be connected only to batteries with a
nominal voltage of 12 volts. The unit will not operate from a 6 volt battery
and will sustain permanent damage if connected to a 24 volt battery.
4.2 CONNECTION TO POWER SOURCE
The Vector Power Inverter comes equipped with battery clip cables for connection
to the power source:
To operate at full 750 watts , either use the battery clip cable (supplied) or directly
wire to the power source with user supplied wire and fuse. Use wire #8 AWG for
lengths of four feet or less and #6 AWG for lengths to 10 feet.
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:
Use the provided cables and connect the Vector Power Inverter directly to the 12
volt power source as follows:
1. Make sure the Vector Power Inverter power is turned off and that no
flammable fumes are present in the installation area.
2. 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.
3. 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.
4. Make sure all connections between battery clips and terminals are secure.
Direct Hardwiring to Power Source:
Use #8 AWG wire if the inverter to power source connection is 4 feet or less. For longer
cable lengths use #6 AWG wire for lengths to 10 feet. In either case, protect the positive (+)
wire from shorts by installing a 150 to 200 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 of the wire to the Positive (+) terminal of the inverter.
5. Connect a length of wire between the inverter’s negative (-) terminal and the DC power
source negative (-) terminal.
