Three Phase Electric Meter Active Energy Measuring Prevent From
Three-phase Active&Reactive Energy Meter adopts the advanced special energy measuring chips and the
multi-rate technology, using the date sampling and SMT technology.
The product is designed and produced according to the practical
situation of the dweller. All the elements inside the meter have
the feature of long-life, high-reliance.

4. INSTALLATION AND CONNECTION:
1. The meter shall be installed in the dry area with good
ventilation condition to ensure safety and reliability during
installation and operation. If the meter shall be installed in the
area with dirty and easily gets damaged, the metering box should be
configured to protect meter against the dirty environments.
2. The dimension of meter is as below: the holes should be digged
ahead accord with the size and the meter bottom should be fixed on
the strong, fire-proof subjects.
5. TRANSPORTATION AND STORAGE:
- The meters should be free from violent collision when being
delivered or sealed off, and the buyer should in accord with the
rules of ZBW003-82/84 for General Technical Conditions Of
Instrument And Apparatus Packaging to transport and store them.
- The meter should be stored in its original pack and the ambient
temperature to keep them should be within -25℃ and 70℃, there are
no corrosive gas in the air.
- The meter should be placed on the shelves in the warehouse and the
stack height should be less than 5 cartons.
