3 Wiring according to EMC (structure of a CE-typical drive
system)
3.1 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:
z
careful structure
z
good shielding
z
good earthing
z
separated cable routing
