Operation on the frequency inverter
 Note!
A label in the terminal box shows the limit values of the
voltages for your motor.
ƒ During operation of the motors on the frequency inverter or during switching
operationonthemains
voltage peaks can occur, which can damage the motor insulation.
ƒ In order to avoid malfunctions, the limit values specified
in the table must not be exceeded:

 Tip!
ƒ For switching operation on the mains you can limit the voltage peaks by
means of a suppressor circuit with RC elements or varistors (not included
in the scope of supply).
ƒ Dimension the suppressor circuit for the respective application case!
