7.3.4.
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.
