Example for accessories required:
S3 = M22-WRK… selector switch with three switch positions
Q31 = DILA-22(…) con DILA… auxiliary contact module
When in the R position (FWD), S3 will use contact 23/24 to apply the enable
signal

to the DS7 soft starter (+A1 control signal terminal). The rotation is
reversed with S3 via the zero position (off) to position L (REV).
The contactor Q31 is activated and switches the enable signal
①
via the
auxiliary contact 53/54 to the DS7 soft starter (control teA1).
