1 Introduction
This manual contains information for users of the Niky S 1-1.5-2-3 kVA models.
You are advised to read this handbook carefully before installing your uninterruptible power
supply, meticulously following the instructions given herein.
The UPS Niky S is only been made for civil or industrial use; it is not in conformity with the standards
for electro-medical equipment.
• The UPS Niky S has been designed to supply data processing equipment. The load applied must
not exceed the one indicated on the rear label of your UPS.
• The ON/OFF button of your UPS does not electrically isolate the internal parts. To isolate your
UPS unplug it from the mains power socket.
• Do not open the UPS container since there may be parts inside with dangerously high voltage
even when the mains plug is disconnected; there are no parts inside that the user can repair.
• The UPS Niky S has been designed to work in closed, clean rooms where there are no inflamma-
ble liquids or corrosive substances and where it is not too damp.
• Do not place near equipments that generate strong electro-magnetic fields and/or near equi-
pments that are sensible to electro-magnetic fields. (engines, floppy disks, speakers, adapters,
monitors, video, etc...)
• Do not pour any liquid on the UPS or inside the UPS.
• Do not place the UPS in humid environment or near liquid, such as water, chemical solution…
• Do not expose the UPS to the direct sunlight or any heat sorces.
• Keep the ventilation slits clean to dissipate the heat of the UPS.
• Use grounded power cable to connect the UPS to the mains supply.
• Do not plug laser printers into the UPS because of their high start-up current.
• Do not plug house electric equipments, such as hair dryer,air conditioner, and refrigerator into
the UPS outlets.

• Take your UPS out of its packing.
• Make sure the mains supply voltage is identical to the one indicated in the label placed on the rear
of the UPS.
• Switch the UPS on by pressing the ON/OF button until the buzzer emits a sound and check it
operates correctly with the mains (green LED on), and the display is on without alarm notifications.
• Switch the UPS off by pressing the ON/OFF button for at least 3 seconds until the LED and the
display shut down.
• After switching off the UPS, connect the load power cable to the UPS output using the outlets
located on the back of the UPS.
• Switch on your UPS and then the load to check it operates correctly with the mains (green LED on).
• Keep the UPS on for 8 hours to recharge battery before using it. UPS can also be used before battery
is completely charged, but in this case back up time available during black out will be shorter.
Light signals:
The color of the LEDs on the front panel has the following meanings :
• Fixed green LED: mains present and regular, batteries recharging
• Green LED flashing every 3 sec: running on battery
• Green LED flashing every 0.5 sec: autonomy in reserve
• Green/red LEDs flashing: test or restart after end of autonomy
• Fixed red LED: failure or battery overload
Acoustic signals:
• Intermittent sound every 3 sec: running on battery
• Intermittent sound every 0.5 sec: autonomy in reserve
• Continuous sound: failure, overload or batteries flat

4 Signals and controls
CAUTION
While wiring the outlet line, make sure the total length of the cable, from the UPS to the
farthest utility, does not exceed 10 metres.
NOTICE
Never disconnect the 230 V power plug while the UPS is operating since this would
disconnect the earthing protection both from the UPS and from the loads connected to it.

5 Overload and automatic shutdown
Your UPS is equipped with a system to measure the power delivered at the outlet; when this exceeds
the set thresholds, the protection and relative signals are activated; shutdown is automatic with a
delay in relation to the size of the overload.
Under the line mode the green led will be light. If the overload is 100% ± 10%; UPS will shutdown
after 5 minutes and go to fault mode. If the overload is 110% ± 10%; UPS will shutdown immediately
and go to fault mode.
Under the battery mode the red led will be flashed.
If the overload is 100% ± 10%; UPS will be shutdown after 5 second and go to fault mode.
If the overload is 110% ± 10%; UPS will shutdown immediately and go to fault mode.
Self test
Automatic self text is executed each time the UPS is switched on, to provide a reliable operation.
Battery Protection
Battery protection: with the mains on, press the ON button for at least 3 seconds to perform the
battery test; if the batteries are working correctly, the UPS will switch to battery operation for
10 seconds, and then return to mains operation. In case of batteries below the minimum charge
level the battery LED will flash for 5 seconds, if there are exhausted batteries or batteries needing
replacing the battery LED will stay on.
Buzzer silencing
The buzzer can be silenced by pressing the ON button for 1 second while the UPS is battery
operated; if no alarm situations are present the buzzer will stay off.
DC start capability
The UPS can be switched on in DC mode (battery operation).
UPS power supplied outlets
This is a line interactive UPS equipped with AVR, that allows to feed the load with a stabilized
output voltage even when mains floats.
Electrical protection
Automatic swith off upon short circuit.
CPU microprocessor control
Green function: if battery is discharging under no load, UPS will shut down automatically to save
battery life.

EMI/RFI filtering:
Bad quality of mains supply can damage electronic appliances because of electromagnetic radio
frequency interferences. The UPS is provided with a dedicated filter to eliminat these disturbances.
Full time surge protection outlet
Connect the appliances not needing for back up protection (printers, fax etc.) to the surge
protected outlet located near the back of the unit.
Software connection Niky S 1-1.5-2-3 kVA
The UPS is equipped with a USB and an RS232 interface, thanks to which it is possible by means of
a computer to access a set of data regarding the operation of the UPS and control the operating
system unattended shutdown.
Software is available as on option for Win98/ME/2000, Novell and Linux, from the website www.
ups.legrand.com without charge. User license is included in the product.
Telephone protection
The Niky S UPS has an integrated, standard RJ11/RJ45 passing telephone connectionthat provides
protection for telephone or network equipment (modem, telephones, etc.) against overvoltage

7 Changing batteries
Caution
Opening, repairing, or replacing parts inside the UPS must always be carried out by specialized
technical personnel only. First of all, switch off the UPS with the ON/OFF button located on the
front panel, then unplug the power cable from the 230V outlet socket.
1) Switch off the uninterruptible power supply.
2) Unplug the power cable from the mains socket.
3) Change the batteries with others of the same type and make, or having the same features
Keep clear from fire to avoid explosion while handling batteries.
Do not open or tamper with the battery case, because it contains toxic electrolyte that could be
harmful for your skin or eyes. Keep out of children’s reach.
NOTICE
The batteries must only be replaced by qualified technical personnel, who will dispose of
them in compliance with the law in force.

8 Possible malfunctioning
The UPS always operates on batteries:
• There is no line voltage
• Line voltage is out of allowed UPS range
• The power supply cable is not correctly connected to mains socket.
• The input circuit breaker has to be reset
• The mains socket is defective
The UPS signals overloading:
• Additional loads to the ones normally connected have involuntarily been connected on the
output line.
• Check all the loads connected to the output
The UPS doesn’t operate in battery mode (it shuts down or immediately signals it is close to the
operating limit):
• The UPS has operated with no mains voltage for a long time and has not been able to recharge
the battery. Recharge it for at least 6 hours by connecting the uninterruptible power supply to
the mains.
• The battery is flat due to not using the UPS for a long period. Recharge it for at least 6 hours by
connecting the uninterruptible power supply to the mains.
• The battery has run down due to being used frequently, to ambient conditions, or to having
exceeded its average service life; it is necessary to change it.
The UPS doesn’t deliver power to the output:
• Check that the loads are correctly connected to the output sockets
