INSTALLTION
Live installation of wiring is strictly prohibited!
The electricity meter shall be installed indoors as far as possible. Special instrument box protection shall be used for outdoor installation. The installation bottom plate shall be fixed on the wall with strong fire resistance and not easy to vibration. There must be no corrosive gases in the surrounding air where the meter is installed. Avoid dust, salt spray, etc.
When using the electricity meter, the wiring must be conducted strictly according to the wiring diagram in the tail cover of the meter. It is recommended to use copper wire for the lead connected to the terminal seat. The screws of the fixed lead in the terminal seat should be tightened to avoid burning the electricity meter due to bad contact and heating.
TRANSPORTATION AND STORAGE
Ammeters must be transported and stored under the original packaging conditions. Products shall not be severely impacted during transportation and unpacking, and shall be transported and stored according to GB / T 25480-2010 Basic Environmental Conditions for Instrument Transportation and Storage and Test Methods as stipulated in 2010. The products should be stored in the warehouse and placed on the platform frame. The stacking height shall not exceed five layers. No corrosive gases shall be present in the stored environment.
