Automatic Voltage Regulator

7. INSTALLATION

Attention! Before connecting the regulator, make sure that all consuming devices con-
nected to the regulator are switched off and the switch  is in OFF position.
• Before installing the AVR, please make sure that total power of all consumers is lower than AVR
output power. Taking into account the starting loads and power factor of consumers, it is
necessary to apply power margin factor with the coefficient 1.2–1.5; but for such equipment as air
conditioners, fridges, etc., it should be 1.5–2.
Attention! When choosing an AVR, it is necessary to know that reduction of input voltage
increases an input current value, consequently, the maximum power of AVR is reduced
too! Such dependence is shown in the graph below:
Output power, %
100
75
50
25
0 100 1 10 120 130
Note. Adhere strictly to such dependence. If the condition stated above is not adhered to,
warranty servicing becomes void!
• Plug the stabilizer power cord  in the wall outlet.
• Turn on stabilizer with switch  (RESET position).
• If the AVR operates properly, green LED  illuminates, and yellow LED  will blink. At the same
time the digital indicator  will show the input voltage. The total delay makes 6 or 180 s depending
on the "ЗАТРИМКА (Delaying)" button (Увімк./Вимк. (ON/ OFF))  position. After the delay time
yellow LED  turns off and digital indicator  will show the output voltage of the regulator. And only
after that you can turn on the connected devices, consumers.
• When the mains voltage exceeds the allowable rate (lower threshold is 140 V, upper threshold is
260 V) the red LED  illuminates, the AVR disconnects the load automatically.
Attention! It is recommended to switch off the AVR and every connected consumer device
when the power supply is dropped.
