The screw terminal at the bottom side of the CombiMaster
Inverter/Charger, offers the following contacts:

By default, the upper two contacts (Remote) of the accessories connector are connected by a jumper to
close the circuit. If desired, use these contacts to connect a remote switch that mimics the main
On/Charge only switch:

case, the CombiMaster Inverter/Charger's main switch must
be in the off position (). Closed = On, Open = Charge only.
