NOTICE!
–
If the relay outputs have to switch inductive DC loads, free-wheeling diodes
must be circuited in parallel to these loads.
–
If the relay outputs have to switch inductive AC loads, spark suppressors
are required.
CAUTION!
The process supply voltage must be included in the grounding concept (e. g.
grounding of the negative pole).
