Ground a large surface area of the
shieldings of digital signal cables. Stray interference on
control cables,
reduction of emissions.
Power Supply Protective circuit to mitigate over voltage or
lightning strikes. Protection of damage
by over voltage.
Preset for EMC: Motor cable
The motor cable is a source of interference and must be carefully laid.
Use the cables recommended by Phytron. They are tested for EMC safety and are
suitable for movement.
The motor and the encoder cable of the driving system must be connected to a large
surface area of the output of the control cabinet and the motor with a low resistance.

The PE lead (green/yellow) of the motor cable should be fixed at the earthing screw
below the MCC-1 motor connector.

The PE lead at the motor side of the cable should be fixed at the motor's earthing
screw.

For EMC compliant wiring it is important to conductively connect the motor cable
shielding mesh with the controller housing. Use the cable clamps at the bottom and
the top side of the MCC-1. Remove the external cable sheath in that range of the
cable where you fix it with one of the cable clamps.

The cables connecting motor and controller should not be interrupted (e.g. by
connectors).

At the motor side the cable's shielding mesh should be connected to the motor
housing at a large area. We recommend to use special EMC type conduit fittings.

In case of motors without adapted conduit fittings the cable shielding must be
connected as near to the motor as possible and has to be applied to PE.
Potential equalization cables
Connect the shielding on all sides for protection from interference.
The difference of potential can cause incorrect currents on the shielding and must be
avoided by potential equalization cables.
