WARNING
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
connected. The maximum permissible input currents are listed in the "Technical
specifications".
● Remove any excessive pollution.

property.
● Observe the instructions regarding installation and operation.
● Always take protective measures before touching any components.
● Do not remove any necessary covers.
WARNING
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.
