NOTICE
● Only install and operate IP20 degree of protection drives in a closed control
cabinet.
Equipment design
The drives are designed for operation in industrial environments where high values
of electromagnetic interference are reached. Safe, reliable and disturbance-free
operation is only ensured if the control cabinet is professionally installed.
Connect all the metallic parts of the control cabinet (side plates, rear panels,

top and base plates) to the frame of the cabinet with good electrical
conductivity. Make the connections as two-dimensional as possible or establish
them using a large number of point-like screw connections
Connect the PE bar and the EMC shield bar to the control cabinet frame

through a good electrical connection established through a large surface area
Connect all the metal enclosures of the devices and supplementary

components installed in the cabinet – e.g. drive or line filter over a large area
and with good conductivity. It is best to mount these devices and
supplementary components on a mounting plate which is bright and offers
good conductivity. Connect them, in turn, to the control cabinet frame and, in
particular, to the PE bar and EMC shield bar over a large area and with good
conductivity
Follow the instructions in section EMC directives [➙ 15] "Connections and

interference suppression"
