TROUBLESHOOTING INSTRUCTIONS
Troubleshooting the 5118/5120 Inverters
Reverse Polarity Fuses
Check to make sure the DC cables are connected to the proper input lug. e Positive (+) DC
cable MUST be connected to the Red or (+) lug on the back of the inverter. e Negative (-) DC
cable MUST be connected to the Black or (-) lug on the back of the inverter. If these cables are
connected backwards either at the inverter or at the battery, the internal Reverse Polarity fuses
will blow. IMPORTANT: ese fuses protect the inverter from damage in the event that the RV
battery is accidentally connected in reverse. A reversed battery connection, even if for only a
second, will cause these fuses to blow. ese internal fuses are non-replaceable.
Check DC Input Voltage
For proper operation of the inverter, the WF-5118/5120 Inverters require a DC input between
10-15 VDC (nominal). If the battery voltage is below 11.0 volts, a Low Battery symbol will
appear on the center display (see Figure 4). Recharge the battery for continued operation. If the
voltage is above 15 VDC, as can happen with some tow vehicle alternators, the WF-5118/5120
Inverter will shut down to protect the internal circuitry.
Inverter Has No Pass-rough
Check the circuit breaker located on the WF-5118/5120 Inverters rear panel. If the breaker is
not tripped, check to make sure the inverter is receiving 115 VAC. NOTE: When the
WF-5118/5120 Inverter is in Pass-rough mode, the Normal (Green) LED on the front panel
will be illuminated to indicate the presence of 115 VAC.
Remote Switch Will Not Turn Inverter ON/OFF
e remote switch will only work if the main Power Pushbutton located on the WF-5118/5120
Inverter’s front panel is in the OFF position. If the remote switch does not turn the inverter ON/
OFF, check the remote switch cable that runs between the rear panel of the inverter to the back
of the remote switch. Make sure the female DB9 connector is fully seated into the male DB9
connector on the rear panel. Tighten the two thumbscrews on either side of the cable connector.
On the opposite end of the cable, make sure the 10-pin single row connector is fully seated into
the back of the remote switch.
If the remote switch will not turn the inverter ON/OFF, replace the remote switch and check for
proper operation. If the remote switch will not work, replace the connecting cable.
