1.2 GPE4890A&GPE4890B Operating Principle
Under normal conditions, every parameter of rectifier modules and distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains fault, the system will be powered by the battery. With the battery discharge, the terminal voltage of the battery starts to descend. When the battery voltage is under 42V±0.5V, the monitoring module reports battery under voltage alarm signal and cuts off the load output, then the power system stops working. When the external AC mains recovers, the system will resume to the normal work state. (All above monitoring data are system default values that users can reset).

5.2 Installation of Rectifier Module
Handles on panel of rectifier module are equipped. When inserting module into the main cabinet, the operator shall clutch the handle with one hand while holding it with the other hand. Slowly push the module into its slot until the connection terminal on back of the module inserted into corresponding socket of system bar in the main cabinet.

When removing module from the main cabinet, first screw off the bolt on panel then slowly remove the module from its slot while clutching the handle.
6. System Maintenance
(1) Failure: yellow LED on rectifier module flickers, communication fails;
Maintenance solution: check the communication network to see whether the internet connection is loose, internet interface is damaged, or network wire is damaged.
(2) Failure: yellow LED on rectifier lights on;
Maintenance solution: check whether the fan is blocked, load current exceeds the max. value; AC voltage is too low, then the auto rate decrease starts; over temperature pre-alarm starts; remote shut-down is started on PC software.
(3) Failure: Red LED on rectifier lights on;
Maintenance solution: check whether the voltage is too high/too low and over/under voltage protection is on; fan is blocked; ambient temperature is too high; load is short circuit or not.
If above mentioned parts are ok but the red LED is still on, then there is problem on the module, please return it to factory for repairing.
(4) Failure: Yellow, red, green LEDs on rectifier are all off;
Maintenance solution: firstly check whether AC input is available or not, if not, then check the electrical circuit; if yes, the module is in malfunction, please return the module to factory for repairing.
