Note:
Maintenance Switches for EMCcompliant connection of FUregulated drives are available
either with shield clips (KS- andKL-enclosure) or with clips mounted on DIN-rails (STM-enclosure).
These clips are used to continue
the cable shield circuit throughthe enclosure.

2The configuration of the Maintenance Switch between FU andmotor allows the use as Disconnector up to 400 Hz and as
Load Switch at frequencies from40 Hz to 100 Hz.

Each Maintenance Switch has asstandard 2 auxiliary contacts,
1 NC and 1 NO. Via the NO(20 ms leading) the FU can beswitched off before the maincontacts of the switch open.

For the rating of the switch
please note that the motor
may have approx. 10 % higher
charging rate due to the higher
loss in FU-operation e.g. a motorwith 7,5 kW rating the motor current has to be determined with
16,7 A instead of 15,2 A.
