6.1 Cleaning
NOTE
Damage to the device during cleaning.
Malfunction possible
→ Do not clean the device using a water jet or high-pressure
washer.
→ Do not use any cleaners containing acids,
bases or solvents.
→ Do not use any pointed or sharp-edged objects to clean.

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.
