5.3 Basics for wiring according to EMC
5.3.1 Shielding
The shielding quality is determined by a good shield connection:
ƒ Connect the shield with a surface as large as possible.
ƒ Use a conductive clamp to connect the shield to the conductive and
grounded mounting plate with a surface as large as possible.
ƒ Unshielded cable ends must always be as short as possible.
5.3.2 Mains connection, DC supply
ƒ You can use unshielded single cores or unshielded cables to connect
the controller and the mains choke to the mains.
ƒ For DC−bus operation or DC supply, use shielded cables.
ƒ The cable cross−section must be dimensioned for the assigned fuse
protection (national and regional regulations).
