•

  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

.

•

 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.

•

 Try to install the UPS in close proximity to a power supply, in such way it will be easier to unplug 

the device as may be required.

Note.  Periodic  maintenance  of  the  device  is  recommended,  as  well  as  periodic  control  of  the 

battery state to provide the device operability.

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.
