Thank you for purchasing this power supply and for your trust in
for your trust in AVANSA®product.
Please read carefully and follow these instructions for installation
and safe use.
This product belongs to the professional range of automatic
uninterruptible power supplies, specifically designed and
manufactured for continuous power supply to solid fuel boilers in case
of main power failure. In the event of a power failure, the UPS will
provide instant power from the battery so the water pumps will keep
running and the boiler will be safely cooled down.
ATTENTION!
This is only a safety device that is used only during power
failure. When using this device please do not supply any longer the
boiler with fuel!
Also, this system can be used to secure other power consumers
that require stability and stable parameters of the electrical energy.
This product should not be used as an inverter (with unlimited
operation from 12VDC source).
The main feature of this device is the output power waveform
when operating on battery, which is pure sine wave, identical to the
main electricity power network of your house. When the main power
of your house is ON, the UPS will charge your battery ensuring a long
lasting battery life. The UPS is only working with an external 12V
battery (or 24V for the 1050W model UPS). It should be used only
lead-acid battery type because the UPS is designed to charge only
this type of battery. The use of a gel battery type might end up with
the explosion of the battery.
ATTENTION!
Be careful when handling the battery. When connecting the UPS
to the battery, avoid wearing personal metal objects (bracelet, chain,
watch, rings, etc.) near the battery because it can cause a short
circuit current that can weld metal material causing severe burns.
Connect the battery respecting the polarity, the red (+ positive) cable
will be connected to the battery + terminal and the black (-,
negative) wire will be connected to terminal -. The cables for
connection to the battery terminals are equipped with metal
connectors. Before making the connection it is recommended to clean
the battery terminals with a brush. Tighten with a wrench the

AVANSA®UNINTERUPTIBLE POWER SUPPLY

connectors to ensure a firm contact. Follow also all the rules from the
battery user manual.
Install the UPS in a dry place, without moisture, away from
water or snow. The place must be large enough to not obstruct the
cooling system of the UPS and free of dust or coal powder that could
block the UPS fan. The place should be well ventilated to prevent
overheating of the system. To avoid electrical shock verify that all
cables are in good condition and free of parts without insulation. The
operation of the UPS may produce sparks. It shouldn’t be installed in
flammable environments.
ATTENTION!
The UPS works only when is connected to the external battery.
It should not be used without the battery connected.
After connecting the battery, plug the main power cable into a power
socket (230V, 50Hz) with ground connection, from the home main
power network. At the rear of the source you connect the equipment
that you want to be protected during a power failure. Follow this
order: connect the battery, connect the main power supply and then
connect the consumer to the UPS. To start, press and hold the power
button (ON/OFF) for 4 seconds.
The operation of the system begins with the automatic detection of
the state of the battery and mains voltage. If the voltage of the
battery is under 10,8V the UPS will consider that the battery is
damaged and it will not start. If the battery is good and the voltage is
low only because of not being charged for a long period of time
please charge the battery with a special battery charger until the
voltage is higher than 10,8V. If the battery voltage is higher than
10,8V and the main supply voltage is between 150-270 VAC the UPS
will supply the consumer and in the same time it will charge the
battery, to bring it to full capacity. Normal operation and battery
charge level can be viewed on the color LCD.
When the main power is OFF (power failure) or when its parameters
are not within normal range the UPS will automatically switch to the
battery, this will be indicated on the LCD and the UPS will start
emitting the alert sound.
When the battery voltage drops below the minimum value (battery is
exhausted) the UPS will increase the frequency of the alert sound and
it will cut OFF the power.

Also, if the consumers that are connected to the UPS will exceed the
maximum power by 110%, the UPS will emit an intermittent acoustic
signal and will automatically close. In case of inductive consumers
like water pumps or electric motors it is recommended to use a
power consumer up to 50% of maximum power of the UPS because
inductive consumers may need a double value of power at start.
ATTENTION! ELECRIC SHOCK HAZARD!
During operation, you must not touch the battery terminals.
To stop the UPS hold the ON/OFF button for 4 seconds until the UPS
emits an acoustic signal and stops.
To extend the battery life it is recommended that you do a cycle of
empty and full charge the battery, at least once in 2 months. Perform
this task if in this period of 2 months were no power failures and the
battery has been kept full all the time.
MAIN FEATURES
Protection features:
- Thermal: if the UPS is heating up the cooling fan is automatically
controlled according to UPS needs, (you don’t need to worry if you
hear the fan working even if the battery is fully charged or there is no
power consumption, the fan is automatically switched on and off
depending on the UPS needs).
- Ground: The UPS stops if there is leakage current.
- Battery (alarm and protection) if the battery is discharged to a
value of 10,8V the UPS will cut off the power to prevent the
destruction of the battery. A fast alarm sound will signalize this.
- Overload protection: if the UPS load exceeds by 110% the rated
power the UPS will stop to avoid own destruction.
- Short circuit protection: the UPS stops in case of short circuit.
- Voltage regulator (AVR) provides a constant voltage to consumers
in a given interval.
- Switch on the battery: the system switches on the battery if the
main power supply disappears, providing uninterrupted power to the
consumers.
- Bypass function: if the electric motor requires more power to start,
when the system can, it will supplement the necessary difference.
- Microprocessor: all functions are supported by a high frequency

microprocessor (32 bit).
- Automation: if the main power network is not in suitable
parameters, the UPS automatically switch to battery.
- Conversion to start the task: in some cases the starting power is
required to be higher than the UPS nominal power. In this case the
UPS solve this issue by supplying up to 110% of its capacity.
Over 110% will beep and will close.
- High charging current: the initial charging current is about 10A, this
will charge the battery in less time than conventional chargers. The
charging current will decrease as the battery is charging up.
- Preserving battery in stand-by mode: after the battery is full the
UPS will keep the battery charged to optimal parameters by giving
from time to time a small charging current.
For optimum results the capacity of the battery must be within
the range of values: 50Ah - 150Ah.
Do not use less than 50Ah batteries because the high initial charging
current of the UPS (up to 10A) will reduce the battery life.
The UPS of 1050W/1500VA will need the use a 24V battery or
two 12V batteries connected in serial connection. If you use two 12V
batteries they should be similar batteries, having the same age and
the same capacity.
Below you can find some teoretical values for a new, fully charged
and very good quality battery, with rezistive consumers.
