Translation of the original operating instructions
6.1 Vibration test
Checking the fan for mechanical vibrations based on ISO 14694.
Recommendation: every 6 months. Maximum vibration severity is 3.5
mm/s measured at the motor’s fastening diameter on the motor support
plate towards and perpendicular to the motor’s axis of rotation.
Fig. 4: Example showing vibration measurement. Positioning of the
sensors will vary depending on the device and the circumstances of
installation.
6.2 Cleaning
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not use a high-pressure cleaner to clean the device.# Do
not use any acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for cleaning
6.3 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.
