2.5 Meter design and operation
2.5.1 Power metering principle is based on transformation of current and voltage input signals into digital signals
and their digital multiplication with signal transformation into pulse recurrence frequency that is proportional to
input power. These pulses summation by microcontroller gives consumed active power. Microcontroller performs
connection between all scheme parts.
2.5.2 Meter design complies with the requirements of IEC 62052-11:2003 and the manufacturer design
documentation. Meter is made in the plastic case.
The meter case generally consists of the top and bottom parts, fitting on perimeter, the transparent window
and removable terminals cover. On the meter front panel are located: LCD display; LED indicator of active energy
metering; optical port elements; «FRAME» button.
2.5.3 Terminals for meter connection to the network, interface lines, pulse outputs are closed by the plastic
cover. Meter external view, image of the terminal plate and numbering of terminal is shown in the Figure 2.2.
Overall and mounting dimensions are given in ANNEX A.

3 METER PRE-OPERATION
3.1 Unpacking
Visual examination should be carried out after unpacking to make sure that there is no mechanical damage,
check the seals existence and their safety.
3.2 Pre-operation
Meters produced by the manufacturer have the factory default settings in accordance with the list given in the
Technical passport. Before installing the meter on the object, it is necessary to change the factory settings if they do
not meet the customer’s requirements according to User Manual.
3.3 Installation procedure
Connect the meter for electric energy metering to the single-phase AC network with the nominal voltage
indicated on the meter panel. For this purpose, remove the terminal cover and connect the lead wires fastening
them in the terminals in accordance with the connection diagram given on the terminal cover or in the Annex B.
ATTENTION! METER CONNECTION SHOULD BE DONE WITHOUT POWER SUPPLY! ONLY PERSONS, WHO
SPECIALLY TRAINED FOR WORK WITH VOLTAGES UP TO 1000 V AND HAVE STUDIED САНТ.411152.165.1
РП, ARE ALLOWED TO WORK WITH THE METER.
In case if the meter is to be connected to AMR system, signal wires should be connected to the telemetery or
interface outputs in compliance with the connection diagram specified in User Manual.
In case if additional sliding fixators are used for meter installation it is necessary to provide limitation of user’s
access to these fixators.
Apply the mains voltage and make sure that the meter is turned on (test LCD is started: all LCD segments are
turned on during 2 seconds, then the current information is displayed).

3.4 Time setting and correction
Time setting/correction and tariff scheldule changing should be performed by authorized representatives of
utility companies.
User has an opportunity to correct time manually according to item 4.2.2 with the FRAME button. Total
correction time is not more than 29 seconds per calendar day. If the clock error is more than 29 s, then the
correction should be carried out within a few days or use the time setting command. Time-back correction is
carried out by seconds zeroing if current second value is not more than 29. Time-forward correction is performed
by setting the value of 59 if the current value of seconds was 30 and more. Date/time of correction and correction
value are fixed in a corresponding event log.
4 OPERATIONAL PROCEDURE
