Wiring a voltage stabilizer

I live in Cambodia where the power supply is,well,unreliable. The local electrical authority connected a new transformer to our house grid and connected to the 22000 volt terminals not 11000,this resulted in blowing most of the residents appliances etc,ours included.

I need to install a 10 kva voltage stabilizer and am after advise on how to wire it. The unit is a Hansinco,10KVA automatic voltage stabilizer.

The unit has three terminals on the left marked;
AC INPUT (In blue)

and three terminals on the right marked;
AC OUTPUT(in red)

The grid is 220 volt.
Note: You may be asking why I don't get an electrician here,well, the local sparkies don't wire "anything" with an earth as it costs money and is considered unnecessary.

Welcome to the forums.

Since this is a US based site we don't know what your electrical even looks like.
Where does this device go...... between the service and the panel ?

Is this what you are putting in ?

Be advised that this device would not have protected your electrical appliances if it had been connected and double your service voltage was sent into the house.

Thanks for the welcome.
Yes,that is the unit and yes it's installed between the service and panel. We get frequent voltage fluctuation here,the stabilizer should negate that.

As for protection of massive over voltage, I intend to install a surge protection device(MCCB) between service and the stabilizer.

What I really want to know is which terminals to connect to,for the voltage stabilizer. Thanks.
