USE
CONNECTIONS AND SWITCHING ON FOR THE FIRST TIME
1) Check that there is a protection device against overcurrents and short circuits in the system upstream from the
UPS. The recommended protection value is 10A (for the 1500VA version) and 16A (for the 3000VA ER version)
with a B or C trip curve.
2) Make sure that there is a connection between UPS and BATTERY BOX and that there are fuses in the battery
disconnector of BATTERY BOX.
3) Power the UPS using the input cable provided.
4) Actuate the I/O switch located on the rear panel.
5) After a few moments, the UPS will switch on, the display will light up, there will be a beep and the icon will
start to flash. The UPS is in stand-by mode: meaning that it is only consuming a small amount of power. The
microcontroller supervising the self-diagnoses is powered; the batteries are charging; and everything is ready for
UPS activation. Battery operation is also in stand-by mode provided that the timer is active.
6) Connect the equipment to be powered into the sockets on the back of the UPS, using the cable supplied or a
cable no longer than 10 metres.
CAUTION: do not connect equipment which absorbs more than 10A to the IEC 10A sockets. For equipment which
exceeds this level of absorption, use the IEC 16A socket only.
7) Check which operating mode is set on the display and, if necessary, see the “Configuring operating modes”
paragraph to set the required mode. For advanced UPS configurations execute the software UPSTools which
can be downloaded from the web site www.riello-ups.com.
SWITCHING ON FROM THE MAINS
1) Press the “ON” button for 1 second. After pressing it, all the icons on the display light up for 1 second and the
UPS beeps.
2) Switch on the equipment connected to the UPS.
When switching on for the first time only: after 30 seconds, check that the UPS is operating correctly:
1) Simulate a blackout by disconnecting power to the UPS.
2) The load must continue to be powered, the icon on the display must light up and there must be a beep
every 4 seconds.
3) When power is reconnected, the UPS must go back to operating from the mains.
SWITCHING ON FROM THE BATTERY
1) Actuate the I/O switch located on the rear panel.
2) Hold down the “ON” button for at least 5 seconds. All the icons on the display light up for 1 second.
3) Switch on the equipment connected to the UPS.
SWITCHING OFF THE UPS
In order to switch off the UPS, hold down the “STBY” button for at least 2 seconds. The UPS goes back to stand-by mode
and the icon starts to flash:
1) If the mains power is present, the I/O switch must be pressed to completely turn off the UPS.
2) During battery mode operation with the timer not set, the UPS automatically switches off after 30 seconds.
However if, the timer is set, press and hold down the "STBY" key for at least 5 seconds to turn off the UPS. For
complete shutdown, press the I/O switch located on the rear panel.

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 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.
(*) 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.

17
REMOTE CONTROL TERMINAL BOARD
The remote control terminal allows for implementation of the REPO function (Remote Emergency Power Off) and to
remotely switch on/off the UPS.
The UPS is provided by the manufacturer with the REPO terminals short-circuited. For installation remove the short circuit
and connect to the device's normally closed contact
In case of an emergency, if the stop device is used, the REPO control is opened and the UPS goes into stand-by mode
and the load is completely disconnected.
Attention: before restarting the UPS, reset the stop device.
The circuitry of the remote control terminal board is self-powered with SELV circuits. Therefore, an external voltage supply
is not required. When a contact is closed, a maximum current of 15mA circulates.
All connections with the remote control terminal board are made through a cable which guarantees a double insulation
connection.
Logic of the connections:
PIN 1-2 REPO
The function is activated when the contact is opened.
PIN 2-3 REMOTE ON, REMOTE ON/OFF
The feature is activated by closing the contact.
Set by default as REMOTE ON, also configurable as REMOTE ON/OFF using UPStools software

18
