Bad
Battery
- Check corrective action in E01 (By-pass Mode)
and restart the charging process by removing
and reconnecting the AC Input Source.
- Check if there is any heavy DC load connected
to the battery as stated in E01 (By-pass mode).
Restart the charging process.
- Change to a new battery.
Reduce load and check if any ventilation of the
unit is blocked.
Reset the GFCI.
Check RJ12 cable connected between the main
and Display panel.
Check AC Input and AC Output wiring.
Consult Customer Service for assistance.
Reduce AC load. Check the AC Circuit Breaker
(Cbr) rating match with the external AC Input
Source Branch Breaker rating.
Reduce AC Load connected to unit. Press and
hold 'Escape' button for 5 seconds to reset AC
Output Switch to provide AC Output from AC
Input Source.
Cool down the battery. Battery charging cycle
will automatically resume when the temperature
drops to below 50 °C.
Check battery and environmental temperature or
add ventilation to the battery compartment.
Check battery and environmental temperature.
The charging cycle will resume when temperature
increases to > 5 °C.
