Diagnostics, faults and warnings

For your personal safety and in order to prevent material damage, follow the instructions
given in section "Safety instructions" (Page 13), especially section "Information about
personal protection" (Page 16). Observe all the safety-related instructions in your product
documentation. Pay particular attention to the safety notices on the product itself.
Every converter is subject to individual inspection and warm up at the factory. Therefore
errors in the device during the initial commissioning can be almost ruled out. In most cases,
faults usually originate from the peripherals such as incorrect wiring or missing agreement
for the respective application.
The most frequent causes of errors during the initial commissioning are shown below:
