- noticeThe PFH value is applicable for the combinations listed in the table for contact load (K) (current through enabling paths) and switching cycle number (n-op/y).
In case of 365 operating days per year and a 24-hour operation, this results in the specified switching cycle times (t-cycle) for the relay contacts.

notice
 
Inductive loads (e.g. contactors, relays, etc.) are to be suppressed by means of a suitable circuit.
 
notice - Wiring example
 
To secure a guard door up to PL 4 and Category #03#
The feedback circuit monitors the positions of the positive-guided NC contacts on the conactors Ka and Kb.
If only one external relay or contactor is used to switch the load, the system can be classified in Control Category 3 to EN 954-1, if exclusion of the fault “Failure of the external contactor” can be substantiated and is documented, e.g. by using a reliable down-rated contactor. A second contactor leads to an increase in the level of security by redundant switching to switch the load off.
The wiring diagram is shown with guard doors closed and in de-energised condition.
