Electrical connection of motor

4.2.2.1

EMC-compliant installation

NOTICE!
Signal interference may be caused if the connection cables are too long.
 Do not exceed a cable length of 3 m.
 Observe the EMC protective measures described here.
EMC filter
 Each electronics and motor supply cable must be installed directly at the unit with two
windings through a suitable ferrite sleeve (e.g. Würth Elektronik No.: 74270090).
