– Connect terminals 51 and 52 and, if required, terminals 54
and 55, in accordance with the circuit diagram.
– Connect terminals 56 and 57 in accordance with
requirements; voltage 125 V max.
– Use separate, shielded lines with a minimum cross-section
2
of 0.5 mm and a maximum length of 1000 m for low
voltages (setpoint/actual value signal lines).
– The screen must be connected on one side to the housing
earth (earth terminal).
Warning
