6.1 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.

; Soiling of the impeller can cause vibration that will shorten the service

life of the fan.

; Severe vibration can destroy the fan.

; In such cases, switch off the fan immediately and clean it.

; The preferred method of cleaning is dry cleaning, e.g. using

compressed air.

; If water is required for cleaning, the preferred method is to perform

cleaning with a conventional water hose or to employ foam cleaning.

; Do not use aggressive cleaning agents!

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.

; If cleaning agents have been used, rinse these off with clean water.

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.
