Carefully comply with the following safety instructions when performing all of the activities.

See alsoSafety information regarding the "Safe Torque Off / safe standstill" function (Page 50)

2.1 Warning symbol on the devicePlease observe the warning symbols attached to the device. The warning symbols have the following meaning:

Warning symbol MeaningWarning: Voltage

Warning: Hot surface

General warning symbol: Observe the explanations about the hazard on the device labels.

For transportation, observe the "transportation markings (Page 62)" on the device packaging.

2.2 Qualified personnelThe product/system described in this documentation may only be operated by personnel qualified for the specific task in accordance with the relevant documentation for the specific task, in particular its warning notices and safety instructions. Because of their training and experience, qualified personnel can recognize any risks involved with handling these products/systems and avoid any possible dangers.

2.3 The 5 safety rulesTo ensure your own personal safety as well as to avoid material damage, always comply with the safety-relevant instructions when carrying out any work. Also carefully comply with the 5 safety rules according to EN 50110‑1 "Working in a no-voltage state" in the specified sequence.


5 safety rules 1. Disconnect the system.

Also disconnect the auxiliary circuits, for example, anti-condensation heating.

2. Secure against reconnection.

3. Verify absence of operating voltage.

4. Ground and short-circuit.

5. Provide protection against adjacent live parts.

To energize the system, apply the measures in reverse order.

2.4 Safe handling

Electric shock from external suppliesEven if the circuit breaker is open, parts of the drive can be under voltage (live) as a result of the auxiliary voltage at the premagnetization, precharging or demagnetization transformers. This danger is not limited to the drive, but can also occur with components that are electrically connected to the drive (e.g. circuit breakers or isolators). Touching live parts can result in death, serious injury and material damage

● Isolate all components that can feed voltage to the drive before commencing work.

Electric shock due to high voltages in operationWhen operating this equipment very high voltages develop. Even after switching off the mains voltage, or while the connected machine is still turning, high voltages can remain for a prolonged length of time. High voltages can cause death or serious injury if the safety rules are not observed or if the equipment is handled incorrectly.

● Operate the device properly.

● Always follow the "The five safety rules (Page 15)" when performing any work.

● Service and maintain the device regularly and correctly.

Electric shock if the grounding switch is defectiveA grounding switch is a component that has an associated certain probability of failure. This means that it is possible that the feedback signal regarding the switching state no longer matches the actual switching state of the grounding switch. This means that if the power unit door is open, hazardous voltages could still be present at the active parts of the drive. Touching the device can result in death or serious injury.

● Check the function of the grounding switch before carrying out any other work at the drive.

● Carefully comply with the 5 safety rules (Page 15).

Safety instructions2.4 Safe handling

3.5.6 Electromechanical door interlock system

The electromechanical door interlock system is designed to protect personnel, and is an integral part of the safety concept. During operation and when the make-proof grounding switch is open, all the doors are interlocked (with the exception of the door for the control section).

The electromechanical door interlock system ensures that the doors for the power unit cannot be opened when the DC link voltage is above a defined threshold value. The control only releases the door interlocking once the circuit breaker is safely open and the grounding switch is closed. You can open the doors once released by the control.

The device cannot be switched on again until all the doors are closed. The doors remain interlocked if the auxiliary voltage fails. For more information, refer to the Chapter "Maintenance"



See alsoOpening the doors (Page 138)

3.5.7 Make-proof grounding switchThe make-proof grounding switch grounds the voltage DC link. This ensures that no hazardous voltages are present in the DC link when the doors are opened.

To ensure that the device functions safely, the actuating lever for the make-proof grounding switch must be withdrawn.

See alsoGrounding using a make-proof grounding switch (Page 137)

3.5.8 Circuit-breaker (provided by the customer)To ensure adequate device protection, the circuit breaker provided by the customer must fulfill the following requirements:

● The maximum time between when the circuit-breaker trips to when a no-current state (I=0) is reached is 80 ms.

● The circuit breaker must be equipped with an undervoltage tripping function.
