WARNING! Use extreme caution when manoeuvring a converter or filter module that
runs on wheels. The modules are heavy and have a high centre of gravity. They
topple over easily if handled carelessly.
1. Read and repeat the steps in
2. Open the cabinet doors.
3. Extract one module from the cabinet as described in section
procedure
4. Check the tightness of the cable connections at the quick connector. Use the
tightening torque table in chapter
5. Clean all contact surfaces of the quick connector and apply a layer of suitable joint
compound (e.g. Isoflex
6. Re-insert the module.
7. Repeat steps 3 to 6 for all remaining modules.

Cooling fans

The cooling fan lifespan depends on the running time of the fan, ambient
temperature and dust concentration. Each module has its own cooling fan.
Replacements are available from ABB. Do not use other than ABB specified spare
parts.
The control program keeps track of the running time of the cooling fan of the
grid-side converter modules. See appropriate Firmware Manual for the actual signal
which indicates the running time.
Fan failure can be predicted from increased noise from fan bearings and gradual rise
in the heatsink temperature in spite of heatsink cleaning. Fan replacement is
recommended once these symptoms appear.
