Con󹪝guration
In the case of 3UG462.-.AA30, A2 and M (GND) are internally electrically connected!
If the load to be monitored and the current monitoring relay are powered from the same system,
terminal A2 is not required!
The load current must always 󹪞ow away through M (GND), otherwise the current monitoring
relay may be destroyed!
