1) Ensure that all the operations described in the paragraph above, “Connections”, have been carried out
correctly.
2) Close the magneto-thermal switch located upstream of the UPS.
3) Press the general switch located on the front panel.
4) The UPS will start up after a few seconds; the display comes on, a beep is emitted and the icon will flash.
The UPS is now in stand-by state: this means that the UPS is in a minimum consumption condition. The
microcontroller is powered and carries out monitoring and autodiagnostic tasks; the batteries are charging;
everything is ready to activate the UPS. There is also a stand-by state during operation from battery if the
timer is activated.
5) Check the settings on the display (see paragraph: Configuration area)

SHUTDOWN
To switch the UPS off, keep the “STBY” key pressed for at least 1.5 seconds. The UPS will return to the stand-
by condition and the icon will start to flash:
a. If the mains is present, the general switch must be pressed so that it returns to its original position
(raised position) to switch the UPS off completely.
b. If the UPS is operating from battery and the timer has not been set, it will automatically switch off
completely after 5 seconds. If however the timer has been set, the “STBY” key has to be pressed for at
least 5 seconds to switch off the UPS. If it is required for the UPS to stay completely switched off when
mains power returns, the general switch has to be pressed (see point a.).
WARNING: the UPS is equipped with an emergency redundant power supply which, in the event of a UPS
failure, will act to avoid the load being shut off by switching it on to the bypass.
If you switch the UPS off simply be pressing the main switch (without first putting it in stand-by as explained
in the manual), the load will still be powered by the bypass.
