6.2 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. 5: Example illustrating vibration measurement. The arrangement of
the sensors depends on the device concerned and the installation
situation.

6.3 Cleaning

To ensure a long service life, check the fans regularly for proper
operation and soiling. The frequency of checking is to be adapted
accordingly depending on the degree of soiling.
DANGER
Risk of injury from rotating fan.
→ Only clean when not in motion. Do not disconnect the fan
from the power supply, just switch it off via the control input.
This will prevent start-up of the fan.
; Dirt deposits on the motor housing can cause overheating of the motor.
