Connecting shielded three-phase cables
A good shield connection is achieved by connecting the shields in the converter cabinet
through a large surface area to the EMC shield rail using EMC shield clamps (PUK shield
clamps). EMC shield clamps (PUK shield clamps) are provided in the accessories pack to
connect to the shield rail.
