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-S… variable
frequency drive with a frame size of FS1 or FS2 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.
