NOTICE
Damage to the drive electronics when switching the line contactor under load
Switching the line contactor (type according to the recommended selection) under load will
cause the contacts to wear prematurely. This can cause the contactor to malfunction, with
subsequent damage to the drive electronics.
• Use a leading switch-o auxiliary contact or use a Voltage Sensing Module (VSM10).
• If this is not possible, then avoid switching the line contactor under load.
Description
The following requirements must be observed when using a line contactor:
• The characteristic values in the technical data apply when the line contactor is selected.
• The cables and conductors to be connected must be dimensioned in compliance with local
installation regulations.
• If the digital output is to be used to control the line contactor, account must be taken of the
switching capacity of this output.
• To limit the switching overvoltage, the contactor coil must be connected to a surge
suppression device (e.g. freewheeling diode or varistor).
