Cable recommendation
Please note the following recommendation from Maschinenfabrik Reinhau-
sen when wiring the device.
Excessive electrical power can prevent the relay contacts from breaking the
contact current. In control circuits operated with alternating current, take into
account the effect of the line capacitance of long control lines on the func-
tion of the relay contacts.

Information about laying fiber-optic cable
To ensure the smooth transfer of data via the fiber-optic cable, you must en-
sure that mechanical loads are avoided when laying the fiber-optic cable and
later on during operation.
