1.2 Operating Principle
 
AC power is first input AC-INPUT MCB and then feed into the rectifier module after lightning proof and filtering. AC-INPUT acts as protection to over load and short circuit to AC power. The user’s battery is connected to the DC output side through MCB BAT and KM2, and the circuit breaker provides disconnection control, over-load and short-circuit protection to the battery.
 
Under normal conditions, every parameter of rectifier modules and power distribution unit are all under control of the monitoring module, operating according to the pre-set parameter or user’s commands. If AC mains faults, the battery will power to the system. With the battery discharge, the terminal voltage of the battery starts to descend. When battery voltage is under -47V±0.5V, the monitoring module sends DC under voltage alarm signal and when battery voltage is under -46.0V±0.5V (adjustable), the KM1cuts off non-priority loads and retaining power to priority loads. If battery voltage drops to -43.0V±0.5V (adjustable), the KM2 will cut off output of priority loads and then the power system will stop working. If the external AC mains recovers, the system will normally work again. (All above monitoring data are system default values and can be reset by user).
 
Except for battery over-discharge protection, battery or load over-temperature protection is prohibitive under default, users can send command to activate or inactivate according to the demanding.

8.2 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. Finally, finish the installation by firmly fixing the screw on the panel to 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.
 
9. System Maintenance
(1) Failure: yellow LED on rectifier module flickers continuously, communication fails;
Maintenance solution: check the communication network to see whether the internet connection is loose or internet interface is damaged or not. 
(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 lower, 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.
