Line Contactors
Line contactors are required for electrical isolation of the drive line-up from the power supply
network.
For selection of the line contactor, the characteristic values in the technical data apply. The
cable routing, the bundling factor, and the factor for the ambient temperature according to
EN 60204-1 must be taken into account in rating the conductors to be connected.
Line contactors must not be switched under load.
When the digital output is used to control the line contactor, the make/break capacity must
be taken into account.
You are advised to connect overvoltage limiters to the contactor coils to limit the opening
overvoltage. See catalog D21.1.
