CONFIGURING THE OPERATING MODE

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 “SEL” button for at least 3 seconds.

• The icon corresponding to the mode currently set lights up.

• To change the mode, press the “ON” button.

• To confirm the mode chosen, hold down the “SEL” button for at least 3 seconds.

POSSIBLE 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 power, so 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.

(*) 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.

ADDITIONAL 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 “C02” appears on the display.

To return to the normal operation mode press the ON and SEL keys again for at least 4 sec..
