When installing the meter, follow the wiring diagram in the user manual for wiring2. The meter should be installed in a dry and stable place, and can be installed indoors to avoid direct sunlight. It should be kept away from moisture, heat, mold, smoke, dust, sand, and corrosive gases. After testing and sealing, it can be installed and used. If it is not sealed or stored for a long time, the test meter should be trusted3. Only experienced electricians or professional technicians can install meter. Please read the manual4. Must be installed on a fire‑resistant wall and not easily shaken5. It is recommended to use copper wire input during wiring to avoid poor contact that may cause the meter to burn6. After the meter is correct, the indicator light will light up, and the load capacity of the meter is between 0.05lb and lmax. If the capacity exceeds the limit, it will cause burnout Package List 1 x Electric Energy Meter 1 x User Manual
