2 Tighten the screw connection of the cable entry securely.
3 Seal cable entries that are not needed with a plug.

4.11.1 Important notes
• All groups are electrically isolated from each other and from all other output circuits.
• Passive mode: An external power supply is necessary to operate (activation) the subsequent
devices (U
ext
).
• Active mode: The signal converter supplies the power for operation (activation) of the
subsequent devices, observe max. operating data.
• Terminals that are not used should not have any conductive connection to other electrically
conductive parts.
