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 supplies
Even 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 operation
When 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 defective
A 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).
