3.5.2.2 - 3-phase AC power supply in accordance with safety standard EN954-1 - category 1 with use of safety input
Note:
For single-phase standards, the power supply is connected to terminals L and N.
QS: Fused isolator: QS must be opened before any intervention on the electrical parts of the drive or motor.
AU: Emergency stop button.
Optional braking resistor. Dissipates the active power returned by the motor onto the drive DC bus in the event of a driving
machine.
Using the safety input means the motor can be stopped in freewheel mode without using a line contactor. The drive’s internal
principles are sufficiently safe to perform a stop using the safety input directly (category 1 of EN954-1).
