CAUTION!
The process supply voltage must be included in the earthing concept (e. g.
earthing of the minus pole).
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.
