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: in case of warranty card loss or discrepancy of numbers you forfeit the right for warranty repairs.
- Do not switch on the speaker system immediately after you bring it into a room from environment with negative temperature! After unpacking, the speaker system should be kept in conditions of room temperature for at least 4 hours.
- Before installing and using the speaker system, read this Manual carefully and keep it for future reference.
APPLICATION
Automatic voltage regulator (AVR) is designed for providing various equipment with high-quality stable electric power supply in conditions of significant and continuous deviations of mains voltage and protecting consumer devices against overload, infiuence of high frequency and impulse interferences.
SAFETY PRECAUTIONS
Before using this device, please read the safety rules carefully:
-
It is strongly forbidden to open the cover of the device, there is high voltage inside. If some problems occur, please read the operation manual carefully and address an authorized service center. For the list of authorized service centers please go to www.real-el.com.
-
Do not let liquid get inside the device, it can cause short circuit or electric shock.
-
In case there are signs of improper operation of the device (sparkling, unusual smells, etc.), unplug the device from the mains immediately and address your nearest authorized service center.
-
It is forbidden to connect the automatic voltage regulator to devices with power consumption higher than its maximum output power. It can cause breakdown of the device.
-
This device is not intended for use by persons (including children) with reduced physical, mental capabilities, lack of experience or knowledge; use of the device by such persons is permitted only under the condition of supervision or instructions for the use of household appliances by persons responsible for their safety.
-
Children should be supervised by authorized personnel to exclude their playing with the appliance.
-
Do not use the appliance with a damaged power cord or plug, or after handling liquids, falling or any other damage. To avoid electric shock, do not attempt to disassemble or repair the appliance yourself. If necessary, contact a specialized service center.
It is strongly forbidden to operate the device in the following conditions:- at temperature higher than 40 °C or lower than 0 C;|
- at temperature higher than 40 °C or lower than 0 °C;
- at humidity level higher than 90 %;
- in direct sunlight or next to heating elements;
- in vibration areas;
- outdoors.
-
In case of fire use only powder fire extinguisher, as water can cause electric shock.
-
The automatic voltage regulator should be installed in proximity to power supply, then it will be easier to unplug the device if necessary.
Caution! There is high voltage inside on the insulation elements which can result in electric shock.

INSTALLATION
Attention! Before connecting the regulator, make sure that all consumer
devices connected 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 increases value of input current, which means that maximum
power of AVR is reduced too! Such dependence is shown in the graph below:
Note. Adhere strictly to such dependence. If the condition stated above is not adhered to, warranty servicing becomes void!
- Consumer devices should be connected to the AVR when it is off.
- Connect the AVR to 230 V household mains and switch it on using switch(.
- If the AVR operates properly, digital indicator#will display the voltage on the AVR output, i.e. the output voltage. Connected consumer devices must be turned on after that only.
- If the mains voltage exceeds the operating range (150 – 270 V), the AVR disconnects the load automatically (connected devices).
Attention! If the AVR is not used for a long time, it is recommended to disconnect the AVR and all consumer devices from the power supply network.
TROUBLESHOOTING
| Problem | Cause | Solution |
|---|---|---|
| The AVR does not start. | 1. The switch is off. |
2. There is no voltage in the power supply network.
3. The fuse has activated. 4.The load connected is too powerful.
| 1. Press the switch once again.
2. Make sure that power supply is available.
3. Disconnect the AVR from the power supply and reset the circuit breaker
4. Disconnect some load.
The AVR is turned on, but there is no output voltage.| The AVR is out of
order.| If the problem is not eliminated, please address an authorized service
center.
The AVR often produces clicking sounds.| Input voltage is very unstable.| It
is normal. The AVR regulates output voltage.
The AVR has disconnected the load. Active red indicator.| Input voltage is
beyond possible regulation range of 150 – 270 V.| When input voltage is
normalized, the AVR tuns on automatically.
If none of the above methods can solve the problem, please seek professional advice at your nearest service center. Never attempt to repair the product by yourself.
