5. 설치
메모: The Power Meter must be installed and serviced only by qualified electrical personnel. Always turn off power before installation.
5.1. 전원 끄기
You need to turn off the main breaker in your electric panel to shut off all of the power in your home. However, the service mains are always live! Then remove screws securing the cover to the panel to access the circuit breakers.
Figure 4: Turning off Main Breaker
5.2. Find a Spot for Power Meter
Find a suitable spot for the Power Meter. You can fit it within your electrical panel or use the mounting bracket to fix it on the wall outside the electrical panel if there is no room.
그림 5: 장착 옵션
5.3. 안테나 설치
Locate the External Antenna outside the electrical panel to ensure that the Power Meter signal is not blocked by metal. The base of the antenna has a magnet and can be adsorbed on iron materials. After that, screw the External Antenna to the Antenna connector.
전력계를 전기 패널에 설치하는 경우 드라이버를 사용하여 전기 패널의 녹아웃 덮개를 뚫을 수 있습니다. 그런 다음 구멍을 통해 외부 안테나 케이블을 넣습니다.
Figure 6: Antenna Installation
5.4. 클amp Main CTs around Service Mains
1. Open the clasps on the Main CTs (3.5mm audio plug) to see the arrow (P1→P2 or K→L) or find it on the sticker on the outside of the clamp. This indicates the direction of the CT.
그림 7: CT Clamp 방향
2. 클amp one Main CT on each main service line. Make sure the arrow on the CT must point towards the breakers! Your system may have 1, 2, or 3 main service lines, and a corresponding number of Main CTs are required.
Figure 8: Main CT Installation (3-Phase)
3. If you have Line/Service-side tap solar, the Main CT must be clamp전기 계량기와 인버터에서 들어오는 전원 사이에 연결이 되어 있습니다.
Figure 9: Main CT Installation with Solar
4. Insert each 3.5mm audio plug of the Main CT into the corresponding audio jack on the top of the Power Meter. The jacks are labeled L1/A, L2/B, and L3/C.
Figure 10: Main CT Plug Connections
5.5. 전원 케이블 연결
전원 케이블을 본체 하단에 찰칵 소리가 날 때까지 연결하세요.
그림 11: 전원 케이블 연결
Secure the N wire from the power cable to the neutral bus bar and the L1 wire to the L1/A breaker pole.
For 3-Phase systems, secure the L2, L3 wires corresponding to the L2/B, L3/C breaker poles.
For Split-Phase systems, only secure the L2 wire to the L2/B breaker pole. The L3 wire needs to connect to the neutral bus bar.
For Single Phase systems, the L2 and L3 wires need to connect to the neutral bus bar.
5.6. 클amp Sub CTs around the Circuit (Optional)
If you don't have Sub CTs (2.5mm audio plug), skip this step.
1. Open the clasps on the Sub CTs to see the arrow (P1→P2 or K→L) or find it on the sticker on the outside of the clamp. This indicates the direction of the CT.
Figure 12: Sub CT Clamp 방향
2. 클amp each Sub CT around the circuit you wish to monitor. Make sure the arrow on the CT must point towards the load or Inverter!
Figure 13: Sub CT Installation
메모: If the circuit you are monitoring can generate energy (such as an Inverter), after all wiring is completed, you must manually set the phase of the circuit in the app settings, otherwise the power measurement will be incorrect.
3. Insert each 2.5mm audio plug of the Sub CT into the audio jack on the side of the Power Meter. Remember the number of the audio jack connected to the circuit you are measuring, and you may need to match it in your app.
5.7. Wiring Reference Diagrams
Refer to the following diagrams for common wiring configurations:
Figure 14: 3-Phase Wiring (Most in European 3-phase homes and US Commercial systems)
