6.1 Vibration testing
Checking of fan for mechanical vibration based on ISO 14694.
Recommendation: Every 6 months. Max. vibration severity is 3.5 mm/
s, measured at the motor fastening diameter on the motor support plate in
the direction of the motor axis of rotation and perpendicular to this.
Fig. 1: Example illustrating vibration measurement. The arrangement of
the sensors depends on the device concerned and the installation
situation.

NOTE
High-voltage test
The integrated EMC filter has Y capacitors. The tripping current
is exceeded when AC testing voltage is applied.
→ Test the device with DC voltage when you perform the
legally required high-voltage test. The voltage to be used
corresponds to the peak value of the AC voltage required by
the standard.
