11.4. Multi connector pin-out and overview
Pin Name Type Function
1 AUX voltage output
+ System
voltage
positive The positive connection to power auxiliary devices, like a GX device.
2 AUX voltage output - System
voltage
negative The negative (ground) connection to power auxiliary devices, like a GX
device.
3 Allow to charge Potential free
contact Turns chargers on or off via a wired signal. Pin 3 can be used as the
signal input for pin 4 and wired e. g. from AUX + or AUX -. See system
examples for correct wiring.
When charging is allowed, the contacts are closed and when not
allowed, the contacts are open.
4
5 Allow to discharge Potential free
contact Turns loads on or off via a wired signal. Pin 5 can be used as the
signal input for pin 6 and wired e. g. from AUX + or AUX -. See system
examples for correct wiring.
When discharging is allowed, the contacts are closed and when not
allowed, the contacts are open.
