AEW 100 wireless measurement module is mainly used for metering three phase active energy on low voltage network. There are functions like RS485 communication and wireless communication on 470MHz in order to help customers check, get and manage the value of energy consumption. This kind of production can be installed in distribution box flexibly, achieving the different demand of measurement and statistics of distribution on different areas and different loadings.
1. Choose W before choosing CG;
2. There is a mobile antenna lay outside can be chosen, and the length of wire is 2 meters.

Installing and Wiring description
Installing description of normal type with piercing
L1, L2, L3 prick in to A, B, C phase respectively, and especially the A phase and N terminal powered for the AEW100. And A, B, C phase transmits the voltage and current to AEW100 by mutual inductor, and then the AEW100 transmits the single to PC via RS485.
First step: Loosing the needle screw and loosing the wire bezel to the top (show as above).
Second step: Open the mutual inductor and rotate the wire bezel to vertical (show as above).
Third step: Installing the mutual inductor correctly refers to the current flow (The current flow towards downward as above).
(The current flow towards upward shown as above)
(The current flow towards the left shown as above)
(The current flow towards the right shown as above)
Fourth step: Close the mutual inductor and put down the wire bezel, and make the wire beside the pricking needle hole, then rotate tightly the screw arbor (show as above)
Fifth step: Rotating the pricking needle screw arbor, and then tight the screw arbor, making cross symbol’s angle between 90 degree to 150 degree.
Sixth step: Match the color with mutual inductor and AEW100 terminal, the locate the AEW100 on the mutual inductor (show as above)
Seventh step: The effect picture of the final installation.
1. Loosening cable should be avoided during installation
2. Measure the temperature of the installation position after full-loading operation of equipment side for more than 1 hour,. The temperature should not exceed 80 ℃.
3. The working temperature of the matching transformer of this product is less than 90 ℃
4.2.2 Installing description of W type without
L1, L2, L3 place on A, B, C phase respectively. A、B、C three-phase voltage signal lines are connected to UA, UB, UC terminals respectively, neutral line is connected to the N terminal. And especially the A phase and N terminal powered for the AEW100. And A, B, C phase transmits the voltage and current to AEW100 by mutual inductor, and then the AEW100 transmits the single to PC via RS485.
Terminals of AEW100-D15、AEW100-D15W、AEW100-D20W、AEW100-D36W
3-phase 4-wire (current connected via CT)
3-phase 3-wire (current connected via CT)
3-phase 4-wire (voltage and current connected via CT)
3-phase 3-wire (voltage and current connected via CT)
Note: CG is optional after selecting W, which means taking voltage from magnetic steel.
