Abstract (en)
[origin: WO0127954A1] The invention relates to an actuator unit (A) which is provided with at least two contactors (1, 2) and a secure control unit (3). A three-phase circuit (4) with a secondary voltage of at least 380 V is opened as soon as at least one of the contactors (1, 2) is deactivated. The control unit (3) opens the three-phase circuit (4) by controlling at least one of the contactors (1, 2) when an emergency stop signal is transmitted to the control unit (3) via a secure disconnecting channel (5). The contactors (1, 2) and the control unit (3) are combined to an installation module (7) which can be mounted and dismounted as a unit.
