load. If not, this means that the load is too
small to be detected.
If the stand-by is not required, turn the Knob
fully to the right.

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
Low battery voltage
Voltage < 1.8V/cell
Deep discharged battery
(voltage <1,5V/cell)
Overheating
Battery over voltage
Short circuit in the outlet
Overload
Inversion of the battery
polarity
CONSEQUENCE
Inverter momentarily
stopped, the green
indicator blinks.
Inverter stopped
Inverter momentarily

In the full counter clockwise position, the
sensibility is minimal (20 W). Do not push on
the screw driver.
NOTE : in this mode the output voltage is
intermittently present at the output
SOLUTION
Automatic restart when the battery voltage
rises
Inverter should be manually restarted
when the battery as reach 2V/cell
Automatic restart when the temperature
reaches the normal range.
Wait until the battery voltage reaches the
correct level.
Push the ON/OFF switch to reactivate the
inverter.
Eliminate the short circuit.
Push the ON/OFF switch to reactivate the
inverter.
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.
