STUDER INNOTEC AJ
AJ V2.1 6/24
Safety
The inverter is electronically protected. But protection against polarity inversions of the
battery occurs with an internal fuse, except for AJ 2100-12 inverter, which has no
fuse. The following table will show you the different failures and their consequences.
FAILURE CONSEQUENCE SOLUTION
Low battery voltage
Voltage < 1.8V/cell
Inverter momentarily
stopped, the green
indicator blinks.
Automatic restart when the
battery voltage rises
Deep discharged battery
(voltage <1,5V/cell)
Inverter stopped Inverter should be manually
restarted when the battery
as reach 2V/cell
Overheating Inverter momentarily
stopped, the green
indicator blinks.
Automatic restart when the
temperature reaches the
normal range.
Battery over voltage Inverter stopped. Wait until the battery voltage
reaches the correct level.
Push the ON/OFF switch to
reactivate the inverter
Short circuit in the outlet Inverter stopped. Eliminate the short circuit.
Push the ON/OFF switch to
reactivate the inverter.
Overload Inverter stopped. Use the inverter only in the
range of its nominal power.
Regular use in overload
power diminished the
lifetime of the inverter.
Push the ON/OFF switch to
reactivate the inverter.
