Installation of Electric Meter required experienced electrician or professionals._x000D_ 2.Electric meter should be installed in indoor ventilated and dry place, adopt 35mmDIN standard guide type installation, the bottom plate of the electric energy meter shall be fixed to the rigid refractory, non-vibrating wall. _x000D_ 3.The bottom plate of the electric energy meter shall be fixed to the rigid refractory, non-vibrating wall._x000D_ 4. Electricity meters should be installed in protective cabinets in places where there are filth and potential damages._x000D_ 5. The installation should be in accordance with the wiring diagram, preferably with a multi-strand copper wire, avoiding the abnormal or burning of the electricity meter because of the bad contact._x000D_ 6. When the electricity meter is correctly connected to the power grid, the power indicator of the meter is on_x000D_ 7. Electric energy meter should take the lightning protection measures when it is used in the area with more lightning, so as to avoid damaging the electric energy meter by lightning. _x000D_ The load capacity of the electricity meter is 0.05ib ~ Imax (direct access) _x000D_ Power indication: when the green light on, indicates that working power supply is normal _x000D_ Pulse indication: when the red light on, indicates that the power pulse is detected_x000D_ When there is a sampling signal, the pulse light is about 80ms _x000D_ _x000D_ _x000D_ Package Included: _x000D_ 1 x Din-rail energy meter
