• The connected load power must not exceed the rated power indicated in the technical
specifications table.
• Place the UPS in closed rooms with the regulated temperature and humidity of the air. The UPS
case temperature can be risen during its operation, it is a normal phenomenon.
• Do not open the battery: escaped electrolyte is dangerous for the skin and eyes.
• Disconnect the UPS from the mains before connection/disconnection of load cables to the UPS
to avoid electric shock.
• In case of an emergency, turn off the UPS and disconnect the power cord from the mains.
• It is strictly prohibited to open the device case – there is high voltage inside. In case of any
problems, connect to the service center. The list of authorized service centers is available on
www.sven.fi.
• UPS should be serviced by qualified specialists only.
• It is strictly prohibited to use the UPS in the following conditions:
- outdoors;

4. TECHNICAL DESCRIPTION
Operating principle
• Models of SVEN RТ are designed to operate with lead-acid maintenance-free 12 V batteries of
AGM type.
• Models of RТ series fall in the line-interactive uninterruptible power supply of continuous
action with prolonged back-up time. Principle of their operation is based on the transformation
of direct current of external batteries to alternating current. Current waveform at the output is
the regular sinusoidal wave.
• Its primary function is the power supply for household and industrial equipment, which is
critical to the input current waveform (boiler equipment, automation systems with equipment
with program control (servers, databases, etc.) with medical equipment).
Caution! There is high voltage inside on unsolated components,
which can result in electric shock.

ENG
• The device is equipped with the automatic voltage regulator (AVR). The built-in regulator
enables to provide correct power supply at overvoltage/undervoltage of the mains without
going to the battery operation mode.
• The automatic start function provides automatic switching on when there is power supply.
With input voltages 160 V or less, as well as 260 V or more the automatic start is not activated.
• The three-stage switch of charging current enables the user to connect batteries of different
capacities depending on the required time to provide the power backup. It is recommended for the
battery with the capacity 20 – 50 А•h to use the position L (3-5 A) of the switch, with the capacity 50 –
100 А•h to use the position M (7-9 A), with the capacity 100 – 200 А•h to use the position Н (13-15 A).
Recommendations regarding selection of batteries
• Select the capacity of a battery (batteries) depending on the connected load power and required
time of power standby, see the table 1 below. Based on the selected capacity, choose a certain
battery (batteries).
• Storage conditions of batteries must conform to the requirements of the battery producer.
• We recommend to use SVEN SV12170, SVEN SV12500, SVEN SV121000 batteries.
Notes:
• When two or more batteries are used, they should be of one type and have the same capacity (if
their capacities are different, the batteries will have different internal resistance and due to this the
charge level will be different).
• Batteries should be connected in parallel, when several batteries are used simultaneously.
Additional cables (to be purchased separately) will be required to connect extra batteries. When
two or more batteries are connected, the plus terminal of one battery is connected to the plus
terminal of the other battery, minus terminals of batteries are connected similarly. The connecting
cables must have a sufficient cross-section and a minimum length.
Features
• Continuous action with prolonged back-up time
• Built-in automatic voltage regulator
• Pure Sine Wave
• Microprocessor control
• Protection against short circuit in connected load to UPS, as well as against overload
