Automatic Voltage Regulator
7. INSTALLATION
Attention! Before connecting the regulator, make sure that all consumer devices con-
nected to it are off.
Before installing the AVR, please make sure that total power of all voltage consumers is lower
than AVR power. Taking into account the starting load and power factor of voltage consumers, it is
necessary to apply power margin factor of 1.2–1.5; for such equipment as air conditioners, fridges
and other electric motors it should be 1.5–2.
Attention! When choosing an AVR, it is necessary to know that reduction of input voltage

Note. Adhere strictly to such dependence. If the condition stated above is not adhered to,
warranty servicing becomes void!

270 V) the red LED
Attention! It is recommended to switch off the AVR and every connected consumer device
when the power supply is dropped.
8. PAUSE FUNCTION
The Pause mode feature is designed to protect equipment in case of frequent drops of the mains
supply. This is particularly important for consumer appliances with electric motors or compressors.
After power supply has been recovered, the AVR switches on within 6 or 180 seconds, depending
on the " DELAY " button " RESET/ OFF " position.
9. PROTECTION FUNCTION AGAINST HIGH AND LOW INPUT VOLTAGE, OVERLOAD AND
OVERHEAT
The stabilizer is equipped with an circuit overvoltage and undervoltage protection. In the case of

automatically resumes operation.
In case of overload or short-circuit AVR power switch
