3.3 Installation procedure3.3.1 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.

Meter with a current range The length of the stripped wire, mm Wire cross-section diameter2, 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

3.4.1 Pulse output connectionThe meter features TM1 pulse output. The output may be used (programmed) as the main transmitting output

device of active or reactive energy, with parameters according to IEC 62052-11:2003, IEC 62053-21:2003 and IEC 62053-23:2003. The output is implemented on transistors with an “open” collector and is intended for switching DC voltage. Nominal supply voltage (10±2) V, maximum allowable value is 24 V.

The value of the switched nominal current is (10±1) mA, the maximum allowable value is 30 mA. By default, TM1 generates pulses proportional to the imported and exported active energies (Ai + Ae). The output can be reconfigured to generate pulses proportional to the individual type of measured energy or as a relay (for details, see САНТ.411152.068-05.1 РП).

To ensure operation of the pulse output, it is necessary to supply DC voltage according to the diagram shown in Figure 3.2

3.4.2 Connection of meter interfacesThe meter provides data exchange with external data processing devices through its optical port and one of the

interfaces, according to the meter modification, in accordance with GOST IEC 61107-2011 protocol and DLMS (for more details, see САНТ.411152.068-05.1 РП).

The optical port is designed in accordance with GOST IEC 61107-2011. The optical port is intended for local connection of the meter via an optical probe connected to the PC serial port.

3.4.2.1 RS485 interface connectionThe meter versions with an RS485 interface make it possible to combine up to 256 devices (meters) on one

common bus. When connecting two or more metering devices, it is necessary to assign an individual address for each one (for details, see САНТ.411152.068-05.1 РП).

The meter’s RS485 interface connection diagram is shown in Figure 3.3.If the ground potentials at the installation sites of meters and data concentrator units (DCU) are equal, then it is

enough to connect pin 11 to the zero potential point, otherwise take potential equalization measures.In the event that the length of the communication lines does not exceed several meters and there are no sources

of interference, then the connection diagram can be significantly simplified by connecting the meter to the DCU or PC using only two signal wires A and B.

The exact resistance value of the termination resistors3, as well as the need to use them, should be determined during the preliminary survey of the facility. In general, if the communication line is up to 1000 m and the exchange rate is up to 9600 bd, the use of termination resistors is not recommended4.

3.4.2.2 Connection of PLC, GSM, Ethernet, radio interfacesThe connection of the CE208 meter to the PC via communication modules is described in detail in

САНТ.411152.068-05.1 РП. 3 It also depends on the cable brand, its length, linear resistance, as well as the input impedance of all other receivers in the line.4 If the termination resistor is already installed inside the data concentrator unit, it can be disconnected using the appropriate

microswitches (jumpers) of the data concentrator unit.

Note – Biasing resistors (+R) and (-R) (nominal 100 kΩ) are installed in the meter and are always connected to the A and B lines, respectively. When it is necessary to connect external biasing resistors (resistance of 560 Ω), you should: make contact between pin 9 and pin 12, in this case the +R resistor installed in the meter is activated; between pins 10 and 11 install an external (-R) resistor with a resistance of 560 Ω. In order to avoid line overload, activation of biasing resistors with a resistance of 560 Ω, as a rule, is only performed for the extreme meters.

3.4.2.3 To exchange data via the optical interface, an optical probe in accordance with GOST IEC 61107-2011 is used.

3.5 Lithium cell replacementIn the meter, an integrated CR14250BL-VY lithium cell or equivalent is used for the real-time clock.The lithium cell should only be replaced by a service company or in the workshop of the utility or organization that

is authorized to repair and check the meter.In the meter, it is necessary to remove the seals of the utility, the service department and state verification,

remove the meter cover, and remove the top meter board from the connector. Solder out the lithium cell from the board and replace it. To replace the lithium cell, it is necessary to comply with the polarity using the symbols on the board. CR14250BL-VY lithium cell by EEMB is recommended. The lithium cell should have the following technical specifications: supply voltage +3.0 V; capacity at least 900 (mA•h); working temperature range from minus 40 to 85 °C; self-discharge max 1% per year.

After replacing the lithium cell, set the date and time, initialize the electronic seal of the body (see САНТ.411152.068-05.1 РП). After replacing the lithium cell, install the board in its original place, close and seal the meter, and verify it. With each replacement, it is necessary to make a note in the Data Sheet – who replaced the lithium cell, when and the type of the replacement battery.

In the meter, it is possible to install an additional lithium cell (in case that the integrated battery is discharged) without opening the meter body. To connect (or replace) it, remove the cover of the clamps (Figure 3.1) and remove the lithium cell holder, install a new lithium cell in the holder, then reinstall the holder. CR2032 lithium cell or equivalent is recommended. The lithium cell should have the following technical specifications: supply voltage +3.0 V; capacity at least 250 (mA•h); working temperature range from minus 40 to 85 °C; self-discharge max 1% per year.

Note — When the meter is turned off, replacing the lithium cell will stop the clock (the LCD displays «Attention» ), so after the replacement of the lithium cell, you must program the current time («Attention» icon will disappear).

4.2 Viewing total accumulated values (on an accrual basis)The amount of active imported, active exported (only for bi-directional meters), reactive imported and exported

energy on an accrual basis, cumulatively and by tariffs is available for viewing on the meter’s LCD in the first group of parameters.

The meter keeps record metering to tariffs, according to the specified tariffing parameters and the time of the built-in clock. The current tariff and the type of energy measured is displayed on the meter’s LCD with the corresponding OBIS code (in the upper left corner of the LCD indicator (see Figure 4.1)), according to the scheme given in Table 4.2.

In the event of an overcurrent in the circuit of the neutral wire by 5 (or 10)% relative to the current in the circuit of the phase wire and the allowed metering by the neutral wire, the consumption metering is performed via the neutral wire. In this case, «N» symbol will be displayed on the LCD.
