7. Maintenance Precautions
In the later stage of installation and use, the iron lithium battery can be simply maintained
and inspected, because of its maintenance-free characteristics, the maintenance period
can be extended, such as once every 3 months.
Check whether the pole column and connection lines of LiFePO4 battery are
loosed, damaged, deformed or corroded, and whether the battery case is
damaged or deformed;
Observe the state of the battery pack running indicator light, normal state is green
light, battery pack CAPCITY light only the last flicker, indicating that the battery
power is low, the battery is about to dry off the output;
When there is a failure, the battery pack flashes ALM the red light and sends out
an alarm. Please check whether the battery connection is correct or over-current;
then press the RST reset key to see if the failure is eliminated after the battery
restarts. If it can not be eliminated, please contact the manufacturer to handle, do
not open the battery case;
For a multi-battery parallel application scenario, if one of the battery fails and
needs to be replaced, make sure that the voltage difference between the newly
replaced battery and the other batteries to be parallel is within 2V, if the Voltage
difference is large, High voltage battery pack charge low voltage battery pack
large current, low voltage battery pack charge over-current protection, resulting in
unable to charge;
Record the time and number of power outages, the battery power supply time to
do detailed statistics;

8.1 Undervoltage alarm
ALM indicator lights flicker, RUN operation indicator lights out.
Cause analysis:
(1) The load current is too large that exceeds the battery’s discharge
