Hazardous arcing
Hazards caused by arcing can occur as result of the following factors, for example:
● The input currents are exceeded
● Incorrectly dimensioned circuit breaker or transformers
● Incorrectly connected cables or cables that have not been connected
● Excessive pollution
Arcing can result in death, serious injury or material damage.
● Make sure that the system is properly dimensioned and that the power cables are correctly

Hot component surfaces
Certain components (e.g. heat sinks and reactors) can become very hot during operation.
These components can remain hot for a long time after operation. Contact can result in serious
injury, such as skin burns.
Do not touch hot components even after you have switched off the drive.
Hot anti-condensation heating surface
When the temperature control limit value is reached the anti-condensation heating is switched
on. Once activated, the anti-condensation heating can generate a great deal of heat. Contact
can result in serious injury, such as skin burns.
