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.

top priority corporate goals.
ebm-papst operates an environmental management system which is
certified in accordance with ISO 14001 and rigorously implemented
around the world on the basis of German standards.
Right from the development stage, ecological design, technical safety
and health protection are fixed criteria.
The following section contains recommendations for ecological disposal
of the product and its components.
NOTE
Damage to the device during cleaning
Malfunction possible
→ Do not clean the device using a high-pressure cleaner.
→ Do not use acid, alkali or solvent-based cleaning agents.
→ Do not use any pointed or sharp-edged objects for cleaning
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.
