Safety Instructions
WARNING
● Only those trained and qualified to work with or on electrical equipment are permit‐
ted to operate, maintain and repair this equipment.
● Do not operate electrical equipment at any time, even for brief measurements or
tests, if the equipment grounding conductor is not permanently connected to the
mounting points of the components provided for this purpose.
● Before working with electrical parts with voltage potentials higher than 50 V, the de‐
vice must be disconnected from the mains voltage. Ensure that the mains voltage is
not reconnected.
● In the frequency converters, capacitors are used in the DC bus as energy stores.
Energy stores maintain their energy even when the supply voltage has been cut off.
Frequency converters have been dimensioned in such a way that after the supply
voltage was cut off, the voltage value falls below 50 V within a discharging time of a
maximum of 10 minutes.
