Wiring according to EMC (structure of a CE-typical drive
system)

Basic rules

The structure of a CE-typical drive system will be more efficient by means of wiring according to
EMC. Wiring according to EMC is determined by the type of installation and the care taken.
Figure 2 shows two important rules for installation:
careful structure
good shielding
good earthing
separated cable routing
