WHEN CONNECTING MORE THAN ONE APPLIANCE TO THE INVERTER,
IN COMBINATION WITH A COMPUTER, NOTE THAT IF ONE OF THE
APPLIANCES IS STARTING UP, IT CAN CAUSE YOUR COMPUTER TO
REBOOT DUE TO A SUDDEN VOLTAGE DROP.
WARNING

Turning on the inverter
When all the above requirements are checked and satisfied and all connections are made, it's
time to turn on your Alessi inverter by pushing the power switch in the ' I ' position. After a short
two tone beep, the sinewave shaped output voltage is gently rising until 230V/50Hz ± 1% (or
115V/60Hz ± 1%) is reached, ready to power your appliances.
When the inverter is not supplying power to an appliance for a longer time, it is recommended to
use the inverter in Automatic Standby (ASB) mode to heavily reduce the inverter's own power
draw. In this case the power switch must be pushed in the ' II ' position. In ASB mode the inverter
will generate a testpulse on it's output once per second, to check when there is a load applied.
When the ASB mode is activated (by generating a reversed two tone beep), the blue AC Present
LED will flash continuously for 4 seconds while the inverter outputs a continuous 230V (or 115V)
sinewave. After this 4 seconds the continuous output will change to a pulsed output. Every time this
pulse is generated the blue LED is activated too, in order to indicate that there's a lethal AC voltage
present at the output. When a load is connected to the inverter output (or switched on) drawing
more than approx. 5W, the inverter jumps to the continuous mode immediately, delivering power
to the load. When the load is disconnected again (or switched off) the blue LED starts flashing for 4
seconds and the inverter jumps back to the pulsed output ASB mode. This way the inverter
automatically jumps to a low power 'sleep' mode when there is no power demand on the output.
Note that some loads like TV/video equipment (with standby mode) and alarm clocks need
continuous power so that the ASB mode can not be used.
With some small non compensated loads, it is possible that the inverter jumps from continuous
output to pulsed output and vice versa all the time. In this case you have to connect a small
additional load to the AC output.
IF THE INVERTER JUMPED INTO AN 'ERROR MODE' (SEE CHAPTER 3.1)
DUE TO AN OVERLOAD OR SHORT CIRCUIT, THE INVERTER WILL
AUTOMATICALLY RESTART AFTER ABOUT 18 SECONDS.
In case of a high temperature error, the inverter will automatically restart after it
has reached an acceptable temperature. Right before the inverter will restart, it
will warn you with a short beep.
WARNING
NEVER SERVICE THE AC CONNECTIONS WHEN THE INVERTER IS STILL
RUNNING IN AN ERROR MODE!
THE BUILD IN LARGE ELECTROLYTIC CAPACITORS CAN HOLD
SIGNIFICANT DC VOLTAGE WHEN THE BATTERIES ARE
DISCONNECTED.
To avoid sparks or short inverter operation, it is advisable to switch on the
inverter for 10 seconds after battery disconnection, before you transport the
