6.1 Cleaning

NOTE
The device does not need to be cleaned.

6.2 Safety test

NOTE
High-voltage test
The integrated EMC filter contains Y capacitors. Therefore, the
trigger current is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you carry out the

high-voltage test required by law. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
