single-phase active and reactive power meter, three-phase active
and reactive power meter and power factor meter in the industries
of electric power grids, automation, substation automation, power
distribution automation, intelligent building, and the enterprise's
internal system. To be matched by the client: RS485 communications,
two-way switch output, two-way switch input, and one way analog
output. Time aging: all the products have been time-aged, so that
it can stably work in a long-term to reduce the impact of external
environment on the meter, offering users a satisfactory product.

4. Installation Precautions:
Installing the meter with the power is forbidden!!
The meters should be installed indoor and protected with the
special metering box; and the mounting plate should be fixed
tightly on the anti-flaming and there shall be no harmful substance
such as dust, salt spray causing the corrosion in the air.
The connection process should in accord with the wiring diagram
printed inside the meter cover and the leads should be made of
copper to connect the bottom of the meter terminal that tightened
with the screws to protect the meter from being damaged by the loss
5. Transportation & Storage:
The goods should be free from violent collision when delivery and
being sealed off, and as per the rules of GB/T13384-2008 General
Technical Conditions Of Mechanical and Electronic Products
Packaging to transport and store them.
Stack the inventory and storage on the shelves under the condition
of original package and its height should be no more than 8 levels.
The place to store the goods should be clean and the temperature
should be in the range of -40℃ and 70℃ as well as less than 95% of
relative humidity; And the hazardous substance that would lead to
the corrosion is not allowed to exist in the air .
