2.5 EMC kits for SK 5xxE frequency inverters
There are more optional components such as EMC kits for the SK 5xxE frequency inverters to ensure
optimum and EMC compliant cabling. The EMC kits are allocated to the respective sizes of the
SK 5xxE frequency inverters and come with shield bracket, two fastening screws and a pre-assembled
PE cables and must be ordered as an option. The shield brackets (without shield clamps) are mounted
on the housing as standard/ex factory of SK 700E frequency inverters of sizes 1 to 4 - in the
performance range from SK 700E-151-340-A (-RS2) to SK 700E-222-340-A (-RS2).

Also applies to the SK 700E frequency inverters with optional “onboard” RS232 interface such as SK 700E-xxx-340-A-RS2.
These frequency inverters already come ex factory with shield bracket but without appropriate shield clamps.
Table 19: Overview of EMC kits for SK 5xxE frequency inverters
Information EMC kit SK EMC2-x
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 clamp. 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 clamp. As an alternative, you can also use the EMC kit as a strain relief only (e.g. for connection cable of
a bus system) (heed bending radii!).
For more information and connection details, please refer to the operating instructions BU 0500 or BU 0505 (see
www.nord.com ) for the SK 5xxE frequency inverter series.
