94 VICSION VS500
9.2 Damageable parts maintenance
Some cells in inverter are worn out or the performance descends in the process of usage process, in order
to ensure the stable running of inverter, so the inverter needs to do the preventative maintenance or replace
the part if necessary
9.2.1 Filter capacitor
Pulse current in main circuit will take effect on the performance of aluminum electrolytic filter capacitor, and
the degree of effect has relation with the ambient temperature and usage condition. In normal condition, the
electrolytic capacitor of inverter should be replaced at 4 to 5 years.
When the electrolytic capacitor leaks out, safety valve falls out or main block of capacitor expands, the
corresponding parts should be replaced immediately.
9.2.2 Cooling fan
The lifetime of all the cooling fans in the inverter is about 15000 hours (that inverter is used
continuously about two years). If the fan happens to abnormal noise or vibration, it should be
replaced immediately.
9.3 Storage
If the inverter don’t used for a long time, please notice the following items:
（1） The environment for storage shall be consistent with the following table:
Environmental
Requirement
Remarks
Ambient
temperature
-20℃-60℃
The long-term storage temperature shall not be over 30℃, so
as to prevent deterioration of the capacitance characteristics,
and the environment with condensation or freezing caused
due to temperature shock shall be avoided
Relative
20～90％
Storage
environment
No direct sunlight, no dust, no corrosive or
inflammable gas, no oil, steam, gas, drip or
vibration, with less salt
Plastic membrane sealing and desiccant, etc. can be used
（2）If the inverter is not to be used for a long time, it shall be electrified once every half year for recovering the
characteristics of the filter capacitor, and checking its other functions. During electrification, one
autotransformer shall be used to gradually increase the voltage, and the electrification time shall be over half an
hour.
If inverter is not used for a long time, the performance of internal filter capacitor will descend.
9.4 After sale services
In guarantee time, if the faults are caused by the following cases, certain service cost would be charged.
①Malfunction caused by not following the operation manual or over the standard specification;
②Malfunction caused by repair or refitting by oneself without grant.
③Malfunction caused by the bad-storage.
④Malfunction due to application of inverter for abnormal functional needs.
⑤Damage caused by the fire, salt-corrode, gas-corrode, earthquake, storm, flood, thunder, voltage
abnormal or other force majored.
Even if over guarantee time, our company will provide the paid service forever.
