Duracell Digital inverter 400 Owner's Manual page 32

Problem: The AC load will not operate, error code shows on digital
display and alarm is sounding.
Error Possible Cause
E01
Low voltage shutdown because
battery is discharged.
E02
Over-voltage shutdown because
of high input voltage.
E03
The AC product(s) connected
are rated at more than the
inverter's continuous power
rating; overload shutdown has
occurred.
E04
The inverter has overheated due
to poor ventilation.
Overheating shutdown has
occurred.
E05
The AC products connected
have a surge power that exceeds
the Inverter's surge capability
or the AC products connected
are short-circuited and
shutdown has occurred.
Solution
Recharge battery.
Shorten cables or use heavier
cables.
Verify the charging system is
properly regulated and the battery
is 12 V nominal.
Use a product with a power rating
within the inverter's continuous
power rating (see Table 3).
Turn inverter off and allow to cool
for 15 minutes. Clear blocked fan
or remove objects covering unit.
Move the inverter to a cooler
place. Reduce load if continuous
operation is required.
The products exceed the inverter's
surge capability. Use a product
with a starting surge power within
the Inverter's capability.
Correct the short-circuit condition.
