6.8.3 Mains current
V1.00/EN/00741192/2021-03-30 [IPC 300]
The mains current sensor serves to monitor the mains current and is placed in
the supply line upstream of the EMI filter. A passive current sensor with gal-
vanic isolation must be used.

put.Measuring range e.g. 0 to 100 A
The current range 0 to 100 A is thereby assigned to the signal 0 to 20 mA.
Monitoring itself is performed via the limit value monitoring function, where the
mains current parameter can be found and has to be set. You can configure
the min., max., and hysteresis values here.
