.
Note
If the encoder is supplied via the module, the cable cross section must be selected large
enough for su󹪟cient voltage to be applied to the encoder via the cable in spite of a drop in
voltage. This applies in particular in the case of incremental 5 V encoders.
• A wire end ferrule is not required. If you use wire end ferrules, they must be of the type
without insulating collars in compliance with DIN 46228 Form A, short type!
