regulations (in Germany: VBG 4).

after deenergisation (power terminal and electronic power supply). This is why it is only
permitted to open the unit after a corresponding waiting time.
The power terminals, fan terminals and control terminals may still be live even in the
even of motor standstill.
If work on the activated unit is necessary:
♦ do not touch any live parts.
♦ use only proper measuring equipment and protective work clothing.

Non-observance of warning notices can result in death, severe personal injury or
considerable property damage.
