2A is the maximum load for the relay contacts. Maximum switching voltage:
24 V DC / 50 V AC, maximum switching power: 30 W / 50 VA.
Pin 1 : 24 V operating voltage (in battery operation 12 V), maximum load
capacity 200 mA.
Pin 4
Ground (GND)
Pin 5 : Battery switch-off
When pin 5 is connected to pin 4, the FCU is not supplied by
integrated batteries. This enables the FCU to be remote-
controlled-switched on and off via an external power supply. The
battery will however still be charged, if a power adapter is
connected.
