9.4 Replacement of wearing parts 

9.4.1 Service life 

The wearing parts of drive mainly include the cooling fan and electrolytic capacitor for filtering, 
whose service life is closely related to the running environment and maintenance condition. 
The following table lists the service life of the wearing parts, which can be replaced based on 
the accumulative run time. 

Part 

Service life 

Test condition 

Fan 

≥ 5 years 

Ambient temperature: 40°C 
Load rate: 80% 
Run time: 24 hours/day 

Electrolytic 

capacitor 

≥ 5 years 

9.4.2 Replacement 

The  fan  or  electrolytic capacitor  that  reaches  the service  life  or  has a  damage needs  to  be 
replaced  in  time  to  avoid  affecting  the  normal  use  of  drive.  The  following  table  lists  the 
replacement criteria and method. 

Part 

Symptom 

Criteria 

Replacement method 

Fan 

The shaft bearing is much 
worn out, the blades are 
aging, or the blades do not 
run. 

The blades have 
cracks.   
There are abnormal 
noises or vibrations. 

Loosen the screws, 
remove the fan cover, 
and pull it outward. 
After replacement, 
ensure that the wind 
blows outward. 

Electrolytic 

capacitor 

There is liquid outflow, the 
safety valve is loose, or the 
electrostatic capacitance 
value changes. 

There is breakage in 
the exterior, the safety 
valve is loose, or the 
electrostatic 
capacitance value 
changes. 

Do not replace the 
electrolytic capacitor 
by yourself since drive 
internal components 
are related. Please 
contact the supplier for 
the replacement.
