3. Reattach the fan unit after having cleaned or visually inspected the mo‐
tor or after troubleshooting (see guidelines below). Protect all mounting
screws with LOCTITE 243 (screwlock) and reestablish all connections.
When attaching the power supply connector, particularly ensure the fol‐
lowing:
There is a seal between the connector and the plug on the fan. Ensure
that the cable cannot put the plug under tensile load in order to avoid
inadequate tightness of this plug connection. If necessary, attach the
connecting cable in flush direction with the plug and provide strain relief
at a close distance.
4. Check the fan and the air circulation for proper functioning.
5. Record all maintenance measures in the machine maintenance plan.

Notes on troubleshooting
Failure/fault
Possible cause
Possible action
Fan motor not running
Mechanical blockage
Switch off and de-energize the energy storage device and re‐
move the mechanical blockage
Wrong line voltage
Check the line voltage and reestablish voltage supply.
Faulty connection
Correct the connection.
Motor winding interrupted
Exchange the device
Impeller running untrue Imbalance of rotating parts
Clean the device. If there is still an imbalance after cleaning,
exchange the device.
Overtemperature of fan
motor
Ambient temperature too high.
If possible, reduce the surrounding air temperature.
Unallowed operating point
Check the operating point
Inadequate cooling
Improve the cooling system
Please contact your Rexroth sales partner in case of other failures.
