Chapter 3 Testing, Operation and Maintenance of the Power System
GIE 4820/3A/3.45KW Power Supply System User Manual
Note:
1. Just the person who has been strictly trained professionally is capable of
cleaning and replacing the fan.
2. It is recommended to clean the fan once every 6 months, and replace the fan
with a new one after 3-5 years.
3.4.2 Emergent Process of the Rectifier Module
1. Internal Short-circuit of the Module
The module can be exit from the system automatically when its internal is
short-circuited.
2. Output Over-voltage of the Module
After the module outputs over-voltage due to some reasons, the output of the
module will be locked up. Then the AC input of the module should be cut off until
the indicators are off and the power source can be turned on. If the over-voltage
still exists, the module may be damaged and need replacing.
For multi-module parallel working state, if the load is light, then one module
over-voltage will cause all the modules are in over-voltage state. Then it need
inserting the module one by one and powers on to test the failure module. The
failure module is replaced after it has been confirmed.
