LCD Display Three Phase Electric Meters with Active & Reactive
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.
＊ Use only isolated tools.
＊ Place the meter only in dry surroundings.
＊ Make sure the used wires are suitable for the max current the
meter can measure.
＊ Make sure the AC wires are installed correctly before activating
＊ Do not touch the meter connecting clamps directly with your bare
hands, with metal, blank wire or other material as you will have
the chance of an electricity shock and a possible chance for health
＊ Make sure the protection cover is placed after installation and
has been sealed.
＊ Installation, maintenance and repair should only be done by a
＊ Never break the seals or open the front cover as this might
influence the functionality of the meter.
＊ Do not through, drop, kick or other physical violence to the
meter as there are high precision components inside that will break
or make the meter measure inaccurate.
＊ Do not mount the meter in area's with harm gas, dust, mildew or
insects or on unstable surfaces.
