Maintenance

Pay attention to the warnings, cautions in this manual and particularly the instructions in this section to avoid equipment damage or electrical shock during maintenance operation 

1. Check the equipment regularly during operation in order to find and deal with abnormal conditions timely. 

2. Keep the ambient environment clear and ensure good ventilation. Clean the air inlets as well as outlets and the dust within the equipment regularly. Disconnect the equipment to the mains power when performing the cleaning operation. 

3. The ventilation fans are designed for continuous operation. The lifespan is 5 years. Check the ventilation fans regularly and replace faulty fans timely. 

4. For the first time PQSVG LV STATCOM is powered on after being disconnected to mains power or stored for more than 3 months, please switch on the incoming circuit breaker and let the equipment in the standby mode for at least 10 hours before operation, in order to restore the withstanding voltage of DC capacitors. This purpose of this process is to reform (or reage) the DC capacitors. Without reforming, capacitors may be damaged when the filter starts to operate. 

5. Check the system clock regularly to make sure the time error is less than one minute.
