Replacing fans for the compact device
Procedure
All internal inverter fans are installed at the bottom of the inverter. Proceed as follows to
remove the fans:
1.
Undo the fan replacement screws - wide inverters have more screws than narrow
inverters.
2.
Remove the complete fan plate downwards. The fan connections are made using one
connector.
3.
Replace the defective fan on the removed fan plate.
4.
Reassemble in reverse order.

Maintenance and service of water cooling (option)
Visual inspection
As part of the inspection of the complete system, Siemens recommends that the water
cooling parts are visually inspected every 6 months and a leakage check performed.
Perform the following checks on an annual basis:
●
Check that all of the hose clamps and valve connections that can be accessed are
securely seated.
●
Perform a visual inspection of the hoses (where these are visible) for tears, cracks or
other damage.
We expect an average lifetime of 10 years for the hoses when the specified environmental
conditions are complied with. Values must be taken from the documentation.
You can find further information in the documentation 4BS0698 AL for water cooling
systems.
9.5
Decommissioning
The device components used have no PCB and BeO.
Dispose of the equipment in accordance with the applicable regulations and also with
respect to electrolyte capacitors.
If you want to decommission a device, please contact the Service Center.
