ODE CONFIGURATION
The area of the display shown in the figure displays the active operating mode
and allows the user to choose other modes directly from the display panel.
HOW TO PROCEED:
To access the configuration area, hold down the “SEL1” button for at least 3 seconds.
To change the mode, press the “ON” button.
The icon corresponding to the mode currently set lights up.
To confirm the mode chosen, hold down the “SEL1” button for at least 3 seconds.

OSSIBLE SETTINGS
The UPS is designed to be configured in various operating modes:
ON-LINE
is the mode with the greatest load protection and the best quality of the output waveform (*)
ECO
is the mode with which the UPS consumes the least amount of power, and is therefore the most efficient (**)
SMART ACTIVE:
in this mode, the UPS decides whether to operate in ON-LINE or ECO mode according to a statistic
about the quality of the mains power.
STAND-BY OFF
[Mode 1]: the UPS operates as an emergency power supply. If mains power is present, the load is
not powered, however should the mains supply fail, the load is powered by the UPS.
Additional operating modes can be set through the configuration software.
(*)
The effective value (rms) of the output frequency and voltage is constantly controlled by the microprocessor,
independently from the waveform of the mains voltage, maintaining the output frequency synchronised to the mains within
a configurable range.
Outside this range, the UPS output de-synchronises from the mains supply, moving to the nominal frequency; in this
condition, the UPS cannot use the bypass.
(**) In order to optimise performance, in ECO mode, the load is normally powered by the bypass. If the mains goes out of the
permitted tolerance range, the UPS switches to ON LINE operation. If the mains returns within the permitted tolerance
range for at least five minutes, the UPS goes back to powering the load from the bypass.

DDITIONAL FUNCTIONS
MANUAL BYPASS
Using the Manual Bypass feature, the UPS can be switched to bypass. In this condition the load is powered directly by the
input mains, any disruption in the mains directly affects the load.
CAUTION:
BEFORE CARRYING OUT THE FOLLOWING SEQUENCE OF OPERATIONS, ENSURE THAT THE UPS’S
INPUT AND OUTPUT FREQUENCY COINCIDE AND THAT THE UPS IS NOT OPERATING FROM THE
BATTERY
Attention: even when the UPS is switched on, the load is disconnected in the event of a mains blackout.
If the input mains deviates from the established tolerances, the UPS automatically switches to Stdby mode and disconnects
the load.
To force the UPS into manual bypass mode, press and hold down the ON and SEL keys simultaneously for at least 4 seconds.
The code "C05" appears on the display.
To return to the normal operation mode press the ON and SEL keys again for at least 4 sec.
