Installation instructions

1.For outdoor installation: Add a sun/rain shield to protect the meter from sun/rain.
2.Do not install in high-vibration areas.
3.Avoid exposure to environments with heavy corrosive gases.
4.Do not share power with power-polluting devices (e.g., inverters, welders); use a 5.power conditioner if necessary.
