Figure 54:EMC installation
a Mains connection: Supply voltage, central earthing connection for control panel and machine
b External radio interference suppression filter: Optional DX-EMC… radio interference suppression
filter for longer motor cables or use in a different EMC environment
c Control connection: Connection for the digital and analog control cables, STO function, and
communication via RJ45 plug-in connection
d Motor connection: Connection (PES) between the screened motor cable and the motor’s terminal box,
made according to EMC requirements, with metal cable gland or with gland plate in the terminal box.
e Cable routing: Power cables (A) and control cables (B) spatially routed separately from each other. If
different potential levels need to cross, they should do so at a right angle as far as possible.
f Cable routing: Do not route power cables and control cables parallel to each other in a single cable
duct. If they need to be routed in parallel, they should be in separate metal cable ducts (in order to
meet EMC requirements).
