Follow these steps when connecting the input cable:
- Connect the ring terminal of the fuse cable to the positive terminal on the vehicle starter battery or RV house battery.
- Connect the other end of the fuse cable to the positive terminal of the input cable.
- Ground the negative terminal of the input cable to the chassis of the vehicle or the negative terminal on the vehicle starter battery or RV house battery.
- Connect the input cable to the vehicle battery port on the charger.
Refer to the specifications of the vehicle starter battery or RV house battery and make sure that it can be used with the charger. Always observe the safety instructions of the battery during use.
Do not use the charger with damaged or non-rechargeable batteries.
Avoid reversing the polarity of the positive and negative connections when connecting the input cable and the fuse cable to the vehicle starter battery or RV house battery.
Make sure that the input cable, fuse cable, and output cable are connected firmly to avoid short circuits or loose connections.
After completing the wiring and turning on the charger, if the LED indicator is off and the charger doesn’t work, please check whether the polarities of the vehicle starter battery or RV house battery are connected reversely.
