6.1.2 Device protection
ƒ
In case of condensation, do not connect the controller to the mains voltage before
the moisture has evaporated completely.
ƒ
The controller must be protected by external fuses.
ƒ
Unused control inputs and outputs must be closed according to the intended type of
protection.
