5. Installation
Note: The Power Meter must be installed and serviced only by qualified electrical personnel. Always turn off power before installation.
5.1. Sluk for strømmen
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.
Figur 5: Monteringsmuligheder
5.3. Installer antennen
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.
Hvis du installerer strømmåleren i det elektriske panel, kan du bruge en skruetrækker til at udstanse et knockout-dæksel i det elektriske panel. Før derefter det eksterne antennekabel gennem hullet.
Figure 6: Antenna Installation
5.4. Clamp 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.
Figur 7: CT Clamp Retning
2. Clamp 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 clamped mellem elmåleren og indgående feeds fra inverteren.
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. Tilslut strømkablet
Tilslut strømkablet i bunden af hovedenheden, indtil det klikker på plads.
Figur 11: Strømkabeltilslutning
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. Clamp 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 Retning
2. Clamp 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
Note: 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
