3. Place O-ring onto adapter.
DANGER
Pinching of power and motor connection cables
Risk of fatal injury due to electric shock!
▷ Never damage the insulation of the power and motor connection cables when
inserting into the opening of the frequency inverter.

cables
4. Place the frequency inverter onto the motor adapter of the KSB SuPremE B2
motor and insert the motor cables of the KSB SuPremE B2 motor into the
opening of the frequency inverter.
5. Connect the motor cables as described. (ðSection7.4.3.3,Page40)

Line choke Motor
(asynchronous motor)
Line choke
The line input currents may vary depending on the actual line impedance. In low-
impedance mains, higher currents may occur. To limit the line input current, external
line chokes can be used alongside the line chokes already integrated in the frequency
inverter (in the power range up to and including 55kW).
Output filter
Output filters can only be used in conjunction with an asynchronous motor.
