1. System Overview
 

1.1 GPE48100C system configuration

GPE48100C is composed of frame power distribution, rectifier module (at least one, up to two), and one monitoring module, and the specific optional modules can be found in the following table:

Configuration	Rectifier Module	Monitoring Module	Power Distribution	Remarks
Standard configuration	GPR4850 Series	GPM48-27-EH	AC distribution: 3P terminal block, 63A/2P AC open, C-level lightning protection DC power distribution: 6P terminal block (2 way load, one way battery)	See   module specification for    specific indicators

 

1.2 GPE48100C working principle

The AC power supply enters the rectifier module through the through terminal. Under normal conditions of the system, the rectifier module and the distribution unit are controlled by the monitoring module and work according to their predetermined parameters or user commands. If there is a utility failure, the system will be powered by the battery at this time. With the discharge of the battery, the voltage of the battery terminal starts to drop, and when the battery voltage is lower than 47V±0.5V, the monitoring module reports the DC undervoltage alarm signal. When the battery voltage is lower than 43.2V±0.5V adjustable, the monitoring module controls the contactor KM2 action to shut down the load output, at which time the power system will stop working. When the external utility power is restored, the system will resume normal operation at the same time (the above monitoring data is the default value of the system, the user can reset).
Except for the battery discharge protection, the battery and load over-temperature protection functions are disabled by default, and the user can activate or disable them by issuing commands as needed.

1. Fault phenomenon: rectifier module yellow light flashes continuously, communication failure;

Maintenance: Check the communication network for looseness and damage to the network interface.

1. Fault phenomenon: rectifier module yellow light is always on

   Maintenance: Check whether there is a fan blockage, whether the load current exceeds the maximum current; whether the AC voltage is too low and the automatic derating function appears; whether the temperature is too high and the prealarm appears; whether the remote shutdown function is set in the background interface.

1. Fault phenomenon: rectifier module red light on

       Maintenance: whether the voltage is too high or too low for over-undervoltage protection; whether the
fan is blocked, whether the ambient temperature is too high, whether the load side is shortcircuited;
When the system has a red light on, but not the above, the module is abnormal and needs to be returned to the manufacturer for repair.

1. Fault phenomenon: rectifier module red, yellow and green lights are not lit;

   Maintenance: check whether there is AC input, no input please check the input circuit, there is input
and the light is not on then the module has been damaged, return to the manufacturer for maintenance.
