SmartAX MA5616 Multi-service Access Module
Configuration Guide
Context
The MA5616 supports a Fe-lithium battery set for power backup. Compared with the lead-acid
battery, the Fe-lithium battery features long lifespan, large capacity, optimized discharging
function, fast charging, and flexible environment adaptability. In addition, it supports intelligent
management so that the battery can be automatically charged or discharged.
The Fe-lithium battery is connected to the input port of the power system through a power cable
and connected to the MA5616 through an RS485 serial port cable. When detecting a Fe-lithium
battery, the MA5616 issues a command to the power system to adjust the voltage. The charging
mode of a Fe-lithium battery is the equalizing mode.
When the mains supply fails, the Fe-lithium battery provides power for the MA5616 to ensure
the normal running of the device in a certain period. When the mains supply recovers, the Fe-
lithium battery stops discharging and starts charging.
Procedure
Step 1 Run the emu add command to add an environment monitoring unit (EMU).
Step 2 Run the power supply-parameter command to configure the power distribution parameters.
Step 3 Run the display power system parameter command to query the configuration parameters of
the power system.
Step 4 Save the data.
Run the quit command to quit the H831PMU mode, and then run the save command to save the
data.
Step 5 Configure the Fe-lithium battery monitoring unit.
