7.3.4. Characteristics of the control module
contacts without potential
The contacts without potential are supplied with
special relays.
For the characteristics of the contacts, please see
the table and curves given below.
Notes
– In the case of inductive loads, the contacts must be protected against
overvoltages by means of varistors.
– For the other characteristics, please refer to the IEC 60694.5.4.4.5.4 (Ed.
2.2), Class 3 Standards.
