3.5.5 EMC cable brackets
Frame-size-specific DX-EMC-MNT-… cable brackets can be used to easily
route and secure cables in the connection area of a DC1 variable frequency
drive with a frame size of FS1 to FS3 and an IP20 degree of protection.
These cable brackets are mounted on the variable frequency drive’s mains
connection side (DX-EMC-MNT-…N) and motor side (DX-EMC-MNT-…M)
using the corresponding mounting holes, and are then connected to the
drive’s earthing.
The cable brackets’ integrated hole pattern (M4 screw tread) makes it
possible to secure the cables being connected and relieve any strain on them
by using the corresponding gland plates. It also makes it possible to have a
good 360° EMC connection (PES) in the case of screened cables.
These cable brackets are made of galvanized sheet steel.
