AND MEASUREMENT
THE GLOBAL SPECIALIST IN ELECTRICAL AND
DIGITAL BUILDING INFRASTRUCTURES
Measurement is the basis of all diagnostics.
By simply monitoring consumption, between 8 and 12%
savings can be made. These results can be improved
by implementing specific initiatives.
Encouraged by new standards and directives, measurement
in commercial buildings is increasingly used so that
occupants can easily monitor consumption (heating,
cooling, hot water production, power sockets, lighting, etc).
In addition to electricity meters, Multi-function
measuring units and new protective devices
incorporating measurement functions, Legrand offers
an e.communicating infrastructure that can display
information about electricity consumption, electrical
disturbances on the system, harmonic distortion, etc.

CURRENT
TRANSFORMERS (CT)
Current transformers (CTs) are used to
convert high current values circulating in
cables or busbars to values permitted by
measuring devices (5 A).
There are 2 main CT families:
- single-phase CTs taking bars and/or
cables
- three-phase CTs taking 3 aligned busbars

The current transformer rating is selected
according to the conductor dimensions, but
also according to the maximum prospective
current in the circuit to be measured. In
order to minimise measurement errors,
the rating must be selected as close as
possible to this value.
CTs cannot be used with DC supply.

MOUNTING
Current transformers are available with
several types of fixing. CTs taking cables
can be clipped onto DIN rails. Others,
which take bars, should be fixed in place
by tightening the dedicated screw. They
can also be fixed on a plate using the fixing
points on the bottom.
CONNECTION
The secondary terminals (S1 and S2)
should be connected to the corresponding
inputs on the measuring device (meter or
control unit).

EARTHING THE CT SECONDARY
To ensure the safety of the installation when
the secondary is opened, we recommend
that this is connected to earth in TT or TN
systems.
If an on-load CT has its secondary open, a
high voltage may appear. It is therefore vital
to short-circuit the current transformer
secondary when the rating is changed for
example.
To the load
To reduce the number of cables,
the S2 outputs on the CT secondary
can be grouped together.

FROM THE
SOURCE
The value sent to the meter or

on the direction of mounting on the
bar or cable. To avoid errors, it is essential
to make sure that the CT is in the right
position.
The current flow must enter at P1 (coming
from the source) and exit at P2 (going
towards the load).

ELECTRICITY
METERS
Meters are used to record the electricity
consumed by a single-phase or threephase circuit downstream of the electricity
supply company's metering.
These display the electricity consumption
of the measured circuit and other values
(depending on the catalogue number) such
as current, voltage, power, etc and transmit
this information to a monitoring or energy
management system.
There are 2 electricity meter families:
- direct connection
- connected with CT

ELECTRICITY METERS
PRODUCT SELECTION
A meter should be selected according to
the network (single-phase or three-phase),
its maximum current, required displayed
values and communication type, allowing it
to be run by a monitoring system.
MID certification, in some meters, ensures
the accuracy of metering with a view to
charging out the electricity used.
■ Meters
connected with CT
Meters have 2 types of input: “current” and
“voltage” inputs.
Each current transformer secondary is
connected to the corresponding control
unit inputs (terminals 1-3/4-6/7-9). This
allows the current flowing through the CT
to be measured.
CONNECTION
■ Direct connection meters
The meter is connected in series on the
line to be metered and is protected by the
circuit breaker placed directly upstream.
It must be calibrated to cope with the
maximum current permitted by the meter.

PARAMETER SETTING
After connection, the electricity meter
parameters may need to be changed so
that it displays data consistent with the
currents flowing through the measured
circuit.
The main parameters to be set are:
■ The
connection mode
- Mode A or Mode B (3-phase meter with
CT). This depends on the wiring (Number
of CTs, network with or without neutral,
etc).
■ The metering mode (Dual-tariff meter Cat.
No. 0 046 73) :
- ASY mode: Partial electricity metering
always active
- SYn mode: Partial electricity metering
activated when the external contact closes
(terminals 23/25)
- trf mode: Electricity metering with dual
tariff. The tariff is switched when the
external contact closes (terminals 23/25).
■ The
CT transformation ratio
This corresponds to the value of the current
transformer ratio.
Example: if the CT = 800/5, the CT value will
be 800:5, or 160.
■ The
VT transformation ratio
This corresponds to the value of the voltage
transformer ratio.
Example: if the VT = 600/100, the VT value
will be 600:100, or 6.
When the voltage transformer is not being
used, leave the value at 1.

■ Data
transfer
Electricity meters have pulse type or
RS 485 outputs which can send data to an
operating system. These outputs therefore
need to be configured.
In programming mode, it is possible to
change the pulse weights and duration or
the address, the stop bit and the MODBUS
network parity.

Measure: the electrical (current, voltage,
power, etc) or analogue (temperature) values to check if the installation is working
properly.

connection is used
to activate the 120 Ω

(see page 22).
PARAMETER SETTING
The IP converter parameters (MODBUS and Ethernet) need to be changed. To set the
parameters, connect a PC directly to the converter with a crossover cable.
Enter the user name and password.
By default:
- user name: customer
- password: 0000
Cat. Nos. 0 046 88/89
RJ 45 crossover cable
For the direct link between the PC and the converter, always use a RJ 45 crossover cable
Once the converter is connected and
powered, change your PC's network
parameters (see manual), then open your
web browser and type in the converter IP
address (default address: 192.168.1.100)
Start by changing the MODBUS parameters, then save.
Next change the Ethernet parameters,
then save.
Disconnect the IP converter from the PC
and connect it to your Ethernet network.
The IP converter home page appears.
Select your language.
The various converter parameters are now
displayed.

e-COMMUNICATION & MEASUREMENT WORKSHOP SPECIFICATIONS 21
THE
RS485-MODBUS
NETWORK
PRINCIPLE
The RS485-MODBUS network is a communication network which allows measuring
devices to exchange information with a
computer or a PLC. This network is based
on the master/slave principle.
Legrand measurement products operate
in 8-bit MODBUS RTU protocol.
CONNECTION
To create a MODBUS network, the various
measuring devices with an output, or RS485
interface, must be connected in series (see
diagram below).
The connection must be made using a
shielded twisted pair (eg: Belden 9842 cable)
with minimum cross-section of 0.20 mm²
and impedance of 120 Ω.
To ensure equipotentiality of the shielding,
only one end must be connected to earth.
A 120 Ω resistor (corresponding to the cable
impedance) must be placed on the end of
the bus (first and last device) to prevent
reflected signals.

PARAMETER SETTING
Four parameters are essential to ensure
correct operation of a MODBUS network:
– the MODBUS ADDRESS
– the communication speed
– the parity bit
– the stop bit
MODBUS ADDRESS
Each device must have a different MODBUS address. Each meter or measurement
control unit must therefore be configured
with a different address between 1 and 255.
Communication speed
The communication speed is the data
transmission speed between master and
slave in bps (bits per second). This must
be identical for all devices connected to the
RS485 bus.
Parity bit
This improves the reliability of communication. Legrand recommends setting no
parity bit (none) because other more effective checking methods exist in the whole
monitoring system.
Stop bit
After transmission, the line is set to off for
1 or 2 clock periods depending on the number chosen.
Recommendations for an
RS485 network with Legrand
products:
- Communication speed: 9600 bps
- Parity bit: None
- Stop bit: 1

THE WEB SERVER AND
THE MEASUREMENT
DISPLAY SOFTWARE
The Web server or measurement display
software is used to remotely display and
save data provided by the measuring
devices.
■ The Web server
This can be used to display data on any type
of screen equipped with a web browser
(PC, smartphone, tablet computer, etc).
It has a hard disk for saving data.
■ Measurement display software
This can be used to view measurements on
a dedicated PC on the local area network.
Data is saved to the computer hard disk.
