4.8 Accessories connector (dry contacts)
The screw terminal at the bottom side of the CombiMaster
Inverter/Charger, offers the following contacts:
Remote
switch input
Alarm output
4.8.1 Remote switch
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:
• Use the Remote contacts to use the ignition lock. In this
case, the CombiMaster Inverter/Charger's main switch must
be in the off position (). Closed = On, Open = Charge only.
• Use both contacts to
connect an external switch.
In this case, the
CombiMaster
Inverter/Charger's main
switch must be in the on
position (I). Closed = On,
Open = Charge only.
4.8.2 Alarm output
The lower three contacts of the accessories connector can be used to control external equipment, like
an alarm or light, to indicate the occurrence of a CombiMaster Inverter/Charger alarm. The alarm
outputs support Normally Closed and Normally Open systems and is either alarm triggered, or power
level triggered.
