2.5 EMC Kit
For optimum EMC-compliant wiring, the optional EMC Kit must be used. This includes a shield
bracket, two hammer clips, two fastening screws and a pre-assembled PE cable. The PE cable must
be connected to the appropriate screw on the shielding bracket and to the PE terminal of the
frequency inverter. The connection of further PE connections to the shield bracket is possible with
additional ring cable lugs (SK EMC 2-1 and 2-2).
The EMC Kit provides the possibility of attaching the screening of the motor cable to a large surface of
the frequency inverter (interference source). If necessary, a screened brake resistor cable can be
attached with the second hammer clip.
The screening angle is attached to the two housing screws on the lower edge (below the U-V-W
terminals). The motor cable screening is earthed to a large area of the screening angle by means of
the hammer clip.

Note
The EMC Kit cannot be combined with ...-CP (ColdPlate) devices. Any cable screening must be earthed to a large
area of the mounting surface.
Alternatively, the EMC Kit can be simply used as a strain relief (e.g. for the connection cables of a bus system)
(note the bending radii!).
