ePOWER Battery Charger Manual

Understanding The Error Codes
Error codes will show on the display when either an internal fault such as high internal temperature or
external fault like AC input voltage out of range is detected. The unit will shutdown.
Code Condition Corrective Action
A01 Temperature Sensor (BTS) is defective. Check and or replace the sensor.
E01
Unit shutdown due to low AC
Input (< 85 +/- 5Vac)
Check AC input source. The unit will
automatically recover when the AC Input
voltage return to > 108 +/-5Vac
E02
Unit shutdown due to high AC
Input (>270 +/- 5Vac)
Check AC input source. The unit will
automatically recover when the AC Input
voltage return to < 260 +/-5Vac
E03 Battery is connected backwards Check all battery connections
E04
Charger Internal temperature is too high and
unit has shutdown. Unit will automatically
recover when the unit cools down.
The ventilation of the unit is blocked or
the environmental temperature is high.
Reduce charging current or improve
the ventil
ation near the unit.
E06
High battery temperature >70 °C (>60°C for
Lithium is sensed by the BTS. The unit will
shutdown. Unit will automatically recover
when battery temperature has reduced to 60°C
(55°C for Lithium).
Check battery, charger setting and the
environment the charger is in.
E07
It is not recommended to charge the
battery at extreme low temperatures.
E08 DC Output fuses are blown.
Check battery connection and replace
fuse with the same type and rating.
E09
Unit shutdown due to high battery voltage
(> 17Vdc). Unit will automatically recover
when voltage has reduced to 16Vdc.
Check battery and charger setting.
Check also if there is any other DC supply
connected to the battery banks.
Low battery temperature < -25°C (<0°C for
Lithium is sensed by the BTS. The unit will
shutdown. Unit will automatically recover
when battery temperature reaches -20°C
(>5°C for Lithium).
