Warning: Only install this device if you are familiar with electrical installations and the dangers they can impose. Disregarding the safety precautions can cause serious injuries
The kWh meter is installed after the circuit breaker.
The left side of the kWh meter is connected to 230V~ from the breaker.
The right side of the kWh meter is connected to the SOURCE you want to measure. Such as solar panels, car charger, heat pump, mains connection etc.
Step 1 : Turn off power
Before beginning the installation ensure that incoming power is disabled. Remove the protection cap from the breaker box and verify there is no power with tools intended for this purpose.
Step 2 : Mount kWh meter
Determine the breaker of the source you want to measure. Place the kWh meter on the DIN-rail. Do not forget to click the kWh meter in place using the black tab on the bottom.
Step 3 : Live wire of the source you want to measure
Attach the live wire (brown) of the source to terminal 2 on the top right of the kWh meter.
Step 4 : Neutral wire of the source you want to measure
Attach the blue neutral wire of the source to terminal 4 at the bottom right of the kWh meter. (if you have no neutral wire to the source you can skip this step)
Step 5 : Neutral wire between the breaker and kWh meter
Use an additional wire to connect the neutral terminal on the breaker with terminal 3 (bottom left) on the kWh meter. We recommend using 4mm copper wire for loads up to 32A.
Step 6 : Live wire between the breaker and kWh meter
Use an additional wire to connect the live terminal on the breaker with terminal 1 (top left) on the kWh meter. We recommend using 4mm copper wire for loads up to 32A.
Step 7 : Check connections
Make sure all screws are tightened and pull every wire individually to ensure a strong connection is in place (2.5 - 3Nm).
Step 8 : Turn on power
Close the breaker box with the protection cap and enable incoming electricity. The screen on the kWh meter will now turn on. Installation complete!
Press the Wi-Fi icon button on the kWh meter until the display shows 'AP' blinking. The kWh meter is now in pairing mode. If the AP mode stops blinking, retry.
In the HomeWizard Energy app go to Settings > Meters > Add new meter > kWh meter and follow the instructions.
