2.2 Method of installation
Choose the corresponding hole cutout dimension from the table above , make
a hole in the installation screen, insert the instruments into the hole, place the
four clamping pieces into the clamping holder and push and tighten them by hand.
2.3 Wiring instructions

to the one of instrument case)
Auxiliary power supply (POWER) AC 220V,50/60Hz(Can customize other values)
Electrical quantity signal input(INPUT) : U* andI * represent live wire terminal
of AC voltage input signal and inlet wire terminal of AC current input signal.When
the voltage is higher than the rated input voltage of the product,you should consider
of using PT and installing fuse of 1A at the voltage input port; while the current is
higher than rated input current of the product, you should consider of using the
exterior CT

3.6 Programming operation examples
The measuring range of instruments has been set as the same parameters
provided by users at the factory. Users should check if the input network, voltage/
current measuring range and transformer multiplying power are consistent with
the actual input again before use.

Chapter 4.Cautions
4.1 Please confirm if the power supply, input signal and each terminal wiring of
the meter are correct and reliable before applying the power.
4.2 The instrument must be preheated for 15 minutes to guarantee the precision
of measurement.
4.3 The instrument should not be rapped, knocked and vibrate excessively and
its using environment should meet the technical requirements.
4.4 The meter has been calibrated according to the measuring range required
by the customer upon order. The user should check once again if the measuring
range of the meter is fit with the specifications of the transformer and set the
measuring range again if not.
Chapter 5. Packing and Storage
The instrument and accessories with packing should keep storage conditions
cool and dry and free of wet and corrosive gas with temperature not more than
70°Cand not less than -40°C,and relative humidity≤85%RH.
