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
● Remove any excessive pollution.
Live, moving or rotating parts
Contact with the parts mentioned can result in death, serious physical injury or damage to
property.
● Observe the instructions regarding installation and operation.
● Always take protective measures before touching any components.
● Do not remove any necessary covers.
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.
Do not touch the anti-condensation heating.
