1. BUYER RECOMMENDATIONS
• Unpack the device carefully. Make sure there are no accessories left in the box. Check up the
device for damage; if the product was damaged during transportation, address the firm which
carried out the delivery; if the product functions incorrectly, address the dealer at once.
• Check up the package contents and availability of the warranty card. Make sure the warranty
card has a shop stamp, a legible signature or the seller’s stamp and purchase date, and the goods
number corresponds to that in the warranty card. Remember that at the loss of warranty card or
lack of coincidence of numbers you are deprived the right on warranty repair
• Do not switch on the product immediately after you bring it into a room from environment with
negative temperature! After unpacking, the product should be kept in conditions of room tempe-
rature for at least 4 hours.

Connecting to generator:
The output power of the generator must be higher than the rated power of the AVR. The
frequency of the generator should be in the range of 45 - 65 Hz, and the form of the voltage
at the output should be Pure sine wave. If these conditions are not met, the stabilizer and
generator may not work correctly.
The grounding cable should be selected according to the current. All devices connected to
the AVR must be grounded. Devices without grounding or with untested grounding are
dangerous for the user and may cause malfunction of the electronic control board. Using
the wrong diameter grounding cable can be dangerous for users and device.
WARNING!
High voltage inside which can cause electric shock.

6. INSTALLATION
Warning! Installation and connection must be done by qualified specialists!
Before installing the AVR, make sure that all fixation elements are firmly fixed in the wall!
• For reliable attachment to the wall, it is necessary to determine the type of material (wood, brick,
concrete, plasterboard, etc.) of the wall in order to select the appropriate fasteners.
• The place of installation of the AVR should be close to the mains outlet.
• Install the fastening elements (purchased separately) in the wall, taking into account the
placement of the holes on the back wall of the stabilizer.
• Install the stabilizer on the fasteners.
7. CONNECTION AND OPERATION
Warning! Before connecting the AVR, make sure that all consumer devices that are connected
to it are turned off.
• Before connecting the stabilizer, make sure that the total power of all consumers is lower than the
power of the stabilizer. Also, taking into account starting loads and the power factor of consumers,
it is necessary to take a power reserve with a factor of 1.2–1.5, and for such devices as air
conditioners, refrigerators and other electric motors — 1.5–2 times.
WARNING! When choosing AVR, you need to know that when the input voltage decreases,
the input current increases, and therefore the maximum power of the automatic voltage
regulator decreases! This dependence is schematically shown in the graph below:
Note. In the process of selection and further operation, it is necessary to clearly observe
this dependence. In case of non-compliance with the specified condition, the right to
warranty repair is lost!

Technical support: www.real-el.com
Make sure all connected devices are off, set the AVR power switch to the "OFF" position. Connect
the cables as shown in the connecting figure.
• If the mains voltage exceeds the stabilization limits (lower threshold 150 V, upper threshold 270
V) or in case of overload, the AVR automatically switches off the load.
WARNING! If the AVR is not used for a long time, its recommended to disconnect the AVR and
all connected devices from the mains.
8. "PAUSE" FUNCTION
• This function is intended to protect connected equipment or devices. This is especially important
for consumer devices with electric motors or compressors. After the power supply is restored, the
AVR will turn on after 6 or 180 seconds - it depends on the position of the "DELAY" button.
9. FUNCTION OF PROTECTION AGAINST INCREASED AND REDUCED INPUT VOLTAGE,
OVERLOAD AND OVERHEATING
• The AVR is equipped with a protection function against increased and decreased input voltage
and overload. If the mains voltage deviates above 270 V or below 150 V, the AVR automatically turns
off the load. After the input voltage returns to the range of 150-270 V, the AVR automatically
resumes operation.
• In case of overload or short circuit, the circuit breaker will trip. After eliminating the cause of
overload or short circuit, press the switch button (RESET position) and the AVR will resume
operation.
