5.2 Inspection and Replacement of Quick-wear Parts
5.2.1 Filter Capacitor
The pulsating current of main loop will affect the performance of filter capacitor of aluminium
electrolysis. The affected degree and environment temperature are related to service environment.
Under normal conditions, the inverter shall change electrolytic capacitor once every 10 years. When
electrolyte of electrolytic capacitor leaks, safety valve emits, or capacitance expands, replace it
immediately.
5.2.2 Fax cooling
In BS series pumping inverter, the inverter above BS-22K has cooling fan inside. The service
life of cooling fan is about 15000 houBS-. If fan has abnormal nose or generates vibration, replace
it immediately.
5.3 Storage and Maintenance
5.3.1 Storage
After purchasing inverter, if you do not use it temporarily or decide to store it for a long time,
pay attention to the following items:
1.
Avoid putting inverter on the places in which temperature is high, air is humid, or places
where there is vibration or metal dust. Guarantee good ventilation.
2.
If the inverter is not used for a long term, the internal filter capacitor characteristic will
decrease. Power on twice every two years to recover the characteristics of filter capacitor.
At the same time, check the functions of inverter. During power-on, gradually increase the
voltage through DC power supply. The power-on time shall not be less than 5 hours.
5.3.2 Maintenance
The warranty period of inverter is 2 years(since production date). During warranty period, if
inverter suffers failure or damage under normal conditions, our company provides maintenance
service free of charge. After warranty period, our company also provides paid maintenance services.
During warranty period, if the failure is caused due to the following reasons, some
maintenance fees will be charged.
1. Failure caused by violation of operation manual or standards;
2. Without authorization, user repairs and transforms the inverter.
3. Failure caused by improper storage;
4. Use inverter for abnormal functions;
5. Failure caused by fire disaster, salt corrosion, gas corrosion, earthquake, windstorm,
flood, lightning, abnormal voltage, or other force majeure.
Notice: the warranty scope only refers to inverter body.
