6.1 Input and Output Wiring on the Controller
Operational safety!
All connector screws and screw joints must be adequately tightened. Refer
to the section Mechanical Data on page 19.
After the service cover on the device has been opened, e.g. to complete the
wiring, it must be refitted so that it is in the same alignment as it was prior
to opening. The USB connection must always be below the service screw. If
the mounting is rotated, maintaining the indicated protection classes, as
well as compliance with CSA-Class I, Division 2 (Group C, D) is impaired.
Operational safety!
Improper wiring using the PG screw joints impairs the compliance with the
specified protection classes as well as with CSA Class I, Division 2 (Group C,
D). Please adhere to the following points:
– Do not pass any cables without matching sealing inserts through the PG
screw joints.
– A sealing insert must be used in every PG screw joint.
– Unused bore holes for the sealing inserts must be sealed using sealing
plugs.
– The PG screw joints must be adequately tightened.
For additional information on PG screw joints and sealing inserts please
refer to Mechanical Data on page 19.
Assignment of the wire colors

Pay attention to the wiring diagrams
Depending on the device version, certain signals or interfaces described in
these instructions may not be available. You are also always to pay
