Servicing the separately driven fan motor

• Occasionally inspect the separately driven fan motor, and check it electrically and

mechanically every time the rolling bearings are replaced.

• Replace the permanently lubricated rolling bearing of the separately driven fan motor after

40000operating hours or 5 years at the latest.

9.4 Corrective maintenance

Comply with the following when carrying out any work on the machine:

• Comply with the general safety instructions (Page15).

• Comply with the applicable national and sector-speci󹪝c regulations.

• When using the motor within the European Union, comply with the speci󹪝cations laid down

in EN50110‑1 regarding safe operation of electrical equipment.

If the motor has to be transported, please observe the information and instructions in the

"Transport (Page32)" chapter.

Note

Before commencing removal, you should mark how each of the fastening elements has been

assigned, as well as how internal connections are arranged. This simpli󹪝es subsequent

reassembly.

Avoid damaging the windings protruding out of the stator enclosure when assembling the end

shield.

If possible, assemble the machine on and alignment plate. This ensures that the mounting feet

surfaces are all on the same plane.

Sealing measures

1. Apply the necessary liquid sealant, e.g. Fluid-D, Hylomar, to the centering edge.

2. Check the terminal box seals, and if required, replace these.

3. Repair any damage to the paint, also to screws/bolts.

4. Take the necessary measures to ensure compliance with the applicable degree of protection.

5. Do not forget the foam rubber cover in the cable entry. Completely seal the holes, and ensure

that cables do not come into contact with sharp edges.
