7.2.5 Relay Outputs
NOTE
The relay output connection depends on the
application and the connected actuators.
Interference suppression is required for inductive loads (also relays and contactors).
If this is not possible, protect the relay contacts using a suppressor circuit as
described below.

Provide relay outputs on site with an appropriate
backup fuse!
NOTE
These connections depend on the type of actuator
used, and should only be understood as guidelines.
