5. INSTALLATION AND OPERATION GUIDE
Attention! Before connecting the regulator, make sure that all
consuming devices connected to it are off, and stabilizer
switch is set to «OFF» position.
Attention! When choosing an AVR, it is necessary to
consider that reduction of input voltage increases value of
input current, which means that maximum power of AVR is
reduced too!
•Before installing the AVR, please make sure that total power of
all consumers is lower than AVR power. Besides, take into
account the starting load and power factor of consumers, it is
necessary to apply power margin factor of 1.2–1.5; it should be
1.5–2 for such equipment as air conditioners, fridges, etc
•Connect the necessary equipment to the power outlet (s) of the
stabilizer.
•Connect the regulator to the power network of 230 V.
•Turn on the stabilizer. When the built-in LED lights up the key,
and LED light up: for a short period to test, «Regulating» and
«Delaying/Protection», constantly, «Working».
•When the self-test is complete LED «Delaying/Protection» will go
out and voltage connection to the output receptacles will happen.
If the LED «Delaying/Protection» at the end of the test did not go
out, it is prohibited to operate the regulator to eliminate the
problem.
•«Regulating» LED will light when the regulator to increase or
decrease in the input voltage.

•In case of overload or short circuit the thermal fuse is ready installed on the rear wall is triggered.
Turn on the stabilizer after removing the cause of the overload by pressing the power button.
•When voltage input is more than 285 V or below 184 V regulator will disconnect the load.
«Delaying/Protection» LED will light up.
•«Delaying/Protection» indicator will light up in case of overheating auto-transformer, protection
will work. The load deenergises. After cooling down auto-transformer load power is restored
automatically.
