Samlexpower VR175 Owner's manual - Caution:
If the inverter is to be used for extended periods at power levels above 175
watts, direct connection to the power source is required. Use the provided
cables to connect the VR250/VR400 directly to the 12 volt power source using
the following guidelines:
1. Check to be sure the inverter 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 and tight.
Use # 10 AWG wire if the inverter to power source connection is 4meters or
less. For longer cable lengths use #8 AWG wire. In either case, protect the
positive (+) wire from shorts by installing a fuse or circuit breaker close to
the DC power source (battery) terminal. The fuse should choose 30A for
VR250, 50A for VR400.
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 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 a 30/50A fuse in the fuse holder.
9. Check to be sure that all connections between battery clips, terminals
and fuse are secure and tight.
10. Test the inverter by turning it on and plugging in a 100 watt lamp or
equipment.
11. If the inverter is not properly operating, then refer to the
troubleshooting sections of this manual.
CAUTION:
Loose connectors may cause overheated wires and
melted insulation.
