8.3.3 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 (

Section 8.3.3 "EMC of device").
The use of shielded motor cables is essential in order to maintain the specified radio interference suppression
level.
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
• the standard pulse frequency (P504) is being used
The shielding of the motor cable must be attached at both sides in the motor terminal box and the
inverter housing in the event of wall mounting.
