Converter/charger trips breaker

I have an Inteli-Power 9160A converter/charger that tripped the 45AMP circuit breaker when it went into boost mode. I contacted the manufacturer and they said I should install a 60 amp circuit breaker. I bought a HI-AMP BUSS 60 amp circuit breaker. One terminal is labeled BATT the other is labeled AUX. I'm not sure if I should connect the Charger to the terminal marked AUX and the terminal marked BATT to the battery bank, since the battery is the one drawing the high current. This circuit breaker is also used for trolling motors and the trolling motor is connected to the AUX terminal since the trolling motor is drawing the current. My situation is the batteries will draw the current. Thanks.

    It doesn't matter which way you connect it. They just label them so people don't ask.

    Thanks for the reply, it seems that way to me. It's a 1999 HitchHiker that used to have a 45 watt converter / charger. That went bad, so we replaced it with a higher amp model, but the RV mechanic didn't change the circuit breaker. One cold night with the heater running drained the battery, so I hooked up the generator and the converter put out in boost mode and tripped the circuit breaker. I guess I will go with my gut until I find out more info.

    Not sure if they are bidirectional or not. If so it would not matter. Your reasoning makes sense that the motor terminal would be for the load.

    I am wondering why there is a 45 amp breaker on a 60 amp device. Any idea what size and length of run that wire is it is on?
