•
If a battery is discharged completely or the UPS has not been operated for more than three
months, the battery should be charged completely as well. Failure to comply with storage rules of
batteries will result in their service life decrease.
•
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;
- in dusty environment containing highly inflammable gases;
- at a temperature higher than 40 °C or lower than 5 °C;
- at the relative humidity level higher than 90 %;
- in direct sunlight or close to heating elements;
- in places with elevated vibration.
•
In case of fire use a powder fire extinguisher only, as using water can cause electric shock.
•

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.
Caution! There is high voltage inside on unsolated components,
which can result in electric shock.
