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 to connect the MAXX 750 SST directly to the 12 volt
power source using the following guidelines:
1. Check to be sure the MAXX 750 SST 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 #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 up to 10 feet. In either case,
protect the positive (+) wire from shorts by installing a 150 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.
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).
8. Insert an 150 amp fuse in the fuse holder.
9. Test the inverter by turning it on and plugging in a 100 watt lamp or
equipment.
10. If the inverter is not properly operating, then refer to the trouble-shooting
sections of this manual.
CAUTION: Loose connectors may cause overheated wires and melted insulation.
Check to make sure you have not reversed the polarity. Damage due to
reversed polarity is not covered by our warranty.
