设备安装
Installation
步骤一：选择合适的墙面，对准防逆流控制器的安装孔位钻两个孔，并将膨胀管敲进孔内；
Step1: Choose the position for drilling holes, and then mark the holes position by using a marker,
use the hammer drill to drill hole on the wall. Then put the rear panel on the wall.
步骤二：用自攻螺丝固定防逆流控制器。
Step2: Put the ARPC on the wall, and use the screw to fix the ARPC.

3. 连接电流互感器
Connect CT Sensors Grid (Inputs Grid PHA,PHB,PHC)
CT 方向由电网到负载
Make sure the CT is installed in the right direction: The arrow on the CT must be form grid to load.
CT采样线按照图示方式延长，必须保证R相的CT接 IR，S CT IS，T CT IT。
Wiring the signal wires of the CT as below picture, make sure that the CT which place the R phase line,
the signal wire of this CT must be connected to IRA / IRB of the ARPC. Don’t be in ISA/ISB or ITA/ITB.
