Installation and Usage

The electric energy meter should be installed inside the indoor or outdoor meter box, and the installation base should be fixed on a sturdy and fire-resistant wall. There should be no corrosive gases in the air. The specific installation dimensions are shown in Appendix Figure 1 (recommended installation height is 1.8m); If the machine is severely impacted or the shell is significantly damaged due to falling from a high altitude during the installation process, please do not install or power it on, and contact the supplier as soon as possible.

The electric energy meter should be wired according to the wiring diagram (see Figure 2), preferably using copper wire or copper wire connectors.

Packaging and transportation storage

The transportation and unpacking of this table should not be subjected to severe impact. The storage location should have an ambient temperature of 0 ℃ -60 ℃, a relative humidity of no more than 85%, and should not contain corrosive gases in the air.

The electric energy meter should be stored in the warehouse, and under the original packaging conditions, the stacking height should not exceed five layers. Electric energy meters with unpacked inner packaging should not be stored.
