6.4.3 Grounding and functional ground
In order to maintain conformity with the EMC limit values and ensure the functioning of the
drive amplifier the housing of the drive amplifier must be connected to the control cabinet's
functional ground with low impedance.
When mounting the drive amplifier on a metallic and conductive top-hat rail it must be ensured
that the top-hat rail is connected to the control cabinet's functional ground with sufficiently low
impedance.
•
If the drive amplifier is not sufficiently grounded this may cause radio
interference, leading to non-conformity with the EC EMC Directive.
This can result in malfunctions in the drive amplifier and other
electronic systems.
6.4.4 Shield connection IP20
The Fig. shows connection of the outer shield of the motor cable to the housing of the drive
amplifier. The most favorable way to connect the outer shield of the motor cable to the
housing in terms of EMC is using a metal cable tie or using the shield clamp available as an
accessory.
