time;
• measuring network parameters: voltage frequency, current in the phase and neutral wires, voltage, angle
between current and voltage, active power factor, active, reactive and apparent power;
• measuring Unified Power Quality Index (UPQI) in accordance with class «S» of the measurement process

terminal cover opening; exposure to a magnetic field; reparameterization; maximum power excess; deviation
from the normalized value of voltage level, etc., in accordance with the full list, for details, see the user manual
САНТ.411152.068-05.1 РП);

The meter’s functions are described in detail in the full version of САНТ.411152.068-05.1 РП.
The meter can be used in Automatic Informational and Measuring Systems for Commercial Electric Power
Metering (AMI systems) to transfer the parameters measured or calculated to the control room for controlling,
accounting and distributing electric power.
The measurement results are obtained through processing and calculating current and voltage input signals
performed by the microprocessor circuit on the meter board. The measured data and other information are displayed

on a liquid crystal display (LCD) and can be transmitted via an optical port or one of the interfaces.
The meter has an electronic measuring mechanism performing active and reactive energy measurement in
kW•h and kVar•h, respectively, cumulatively and according to eight tariffs in one or two (for a bi-directional meter)
directions of electric energy metering.
The meter has two additional electronic measuring mechanisms performing active and reactive energy metering
in kW•h and kVar•h, respectively, in one or two (for a bi-directional meter) directions of electric energy metering by
specified events (tariff 9, tariff 10).
Changing time of the measuring mechanism indications complies with the requirements of IEC 62052-11:2003,
IEC 62053-21:2003 and IEC 62053-23:2003.

2.8 Meter design
The meter design complies with the requirements of IEC 62052-11:2003 and the manufacturer’s drawings.
The meter is made in a plastic case.
The appearance of the meter is given in Annex B.
In general, the meter body consists of two parts, upper and lower, mating along the perimeter, a transparent window
and a removable transparent terminal cover.
On the front panel of the meter, there are the following:
• liquid crystal indicator;
• one indicator of active energy metering and one indicator of reactive energy metering. The indicators operate at the
frequency of the main transmitter. The indicators can be used to calibrate the meter.
• indicator of functioning;
Table 2.4 (continued)

18 19
• optical port elements;
• «FRAME» and «VIEW» buttons;
The clamps for connecting the meter to the network, to interface lines and to pulse outputs,
«ACCESS» button are closable with a plastic cover.
In order to access the «ACCESS» button (programming permission), you need to remove the sealing label of the energy
supplying company that installed the meter.
The meter comprises:
• measuring module;
• supply module;
• load control relay (Q) module;
• one or two current sensors (shunts), depending on the version.
3 PREPARING THE METER FOR OPERATION
The meter is supplied with a set of everything necessary for installation at operating site.
The САНТ.411152.068-05.1 РП has a comprehensive set of information for installing the meter at operating site.
3.1 Unpacking
3.1.1 After unpacking, inspect the meter visually, verify that there are no mechanical damages, and check
the presence and integrity of the seals.
3.2 Preparing for operation
3.2.1 The meters produced by the manufacturer have factory settings. Changes to factory settings are made in
accordance with the САНТ.411152.068-05.1 РП by companies authorized to configure the meter.
ATTENTION! PRESENCE OF READINGS ON THE METERING DEVICE IS CAUSED BY CHECKING THE METER
AT THE MANUFACTURER’S, AND DOES NOT ATTEST TO ITS WEAR OR OPERATION.

3.3 Installation procedure
3.3.1 Connect the electric meter to a single-phase AC network with a nominal voltage of 230 V. To do this, remove
the terminal cover and connect the wires by securing them in the terminals of the block according to the wiring
diagram printed on the cover, or given in Annex C.
When installing a meter, the wire (cable) must be stripped of insulation to approximately the amount shown in
Table 3.1. The stripped part of the wire should be smooth, without bends. Insert the wire into the terminal clamp
without tilts. It is not allowed to get a wire with insulation into the terminal, as well as for the stripped area to protrude
outside the block. First, tighten the top screw. Pull the wire lightly to make sure that it has been clamped. Then tighten
the bottom screw. After several minutes, tighten the connection again.
The diameter of the wires connected to the meter is shown in Table 3.1.
Таблица 3.1
Meter with a current range The length of the stripped wire, mm Wire cross-section diameter
2
, mm
5(60) А 27 (1 ÷ 7)
5(100) А 20 (1 ÷ 8)
If it is necessary to connect the meter into an AMI system, connect the signal wires to the interface outputs
in accordance with the wiring diagram.
Make sure that the time and date readings of the meter correspond to the actual values, otherwise set the date
and time (for details see САНТ.411152.068-05.1 РП).
Seal the covers and the «ACCESS» button.
Initialize the electronic seal of the clamp cover (see САНТ.411152.068-05.1 РП).
2The range of the wire diameter is specified based on the possibility of its connection to the meter block. The required cross-section
(and therefore the diameter) of the wire is selected depending on the value of the maximum current
