2.6.2 Chassis mains filters
Various sizes of the chassis mains filters SK HLD 110-500/xxx are available for both frequency
inverter series (SK 700E and SK 5xxE) and all available frequency inverter power levels up to
110.0 kW.
For frequency inverter power levels 132.0 kW and 160.0 kW, other chassis mains filters of type
SK HFD 103-500/300 or SK HFD 103-500/400 in a different version. The chassis mains filters come in
protection class IP20 and are UL-approved (except for the SK HFD 103-500/xxx types).
Mains connection to the mains filters occurs with screw terminals. Depending on the type (shielded or
unshielded) and the length of the motor cable, the chassis mains filters SK HLD 110-500/xxx feature a
radio interference suppression level Class B or C1 with a maximum motor cable length of 25 m and a
shielded cable. For a maximum motor cable length of 50 m and shielded motor cable, the chassis
mains filter complies with EMC limit value classes A or C2. Chassis mains filters SK HFD 103-
500/xxx, however, only comply with radio interference suppression level Class A.
Information Chassis mains filters
The present chapter will describe only some special requirements with regard of a deviating allocation because
the chassis mains filters SK HLD 110-500/xxx or SK HFD 103-500/xxx are used for both frequency inverter series
(SK 5xxE and SK 700E).
