8.1.3 EMC of device
NOTICE
EMC interference to the environment
This device produces high-frequency interference, which may make additional suppression measures
necessary in domestic environments (see 8.1 "Electromagnetic compatibility (EMC)").
The device is exclusively intended for commercial use. It is therefore not subject to the requirements
of the standard EN 61000-3-2 for radiation of harmonics.
The limit value classes are only achieved if
• the wiring is EMC-compliant
• the length of shielded motor cable does not exceed the permissible limits
If a shielded motor cable is used, the shield of the motor cable must be connected to the motor.
