4.3 Electromagnetic compatibility (EMC)
 Follow the instructions in the following chapters to perform an EMC-compliant installa -
tion.
WARNING!
!
The MCS can cause high-frequency interference which can affect the function of electronic
implants and other electronic devices.
 Take appropriate interference suppression measures, particularly during use in residen -
tial environments.
 Observe the notices for EMC-compliant setup.
NOTICE!
Drive electronics with qualified limit values in accordance with EN-61800-3: Category C2
can cause radio interference in residential areas.
 For these drive electronics, take additional measures to limit the spread of radio inter -
ference.
4.3.1 Functional earthing
DANGER!
!
Danger to life through ground leakage currents
≥
3.5 mA

Check the grounding of the devices for proper installation.
The grounding system is essential for discharging parasitic current and for a potential distri -
bution in the system that is as uniform as possible. The most efficient systems have a star or
mesh shape. A star-shaped connection is easier to implement.

Ensure an adequate cross section and a very good electrical ground connection so that
the contact resistances are low not only for the low-frequency currents.
The ground connection can be improved, e.g., by removing the oxide layers from the
ends of conductors with fine sandpaper.
For electrical safety:

Ground in accordance with current standards and guidelines.

Use separate protective conductors (PE) for all necessary parts (e.g., mains supply,
motor, controller).

Keep grounding cable as short as possible.
For functional earthing:

Use a braided shield that is meshed as tightly as possible.

Direct contact with the grounding plate is to be preferred.
Therefore, avoid contact with the controller and then with the grounding plate.

Connections made over a large surface area are to be preferred.
