DESCRIPTION OF THE DEVICE
The three-phase energy meters 7M.38.8.400.xxxx are intended for energy measurements in three-phase electrical power
network and can be used in residential, industrial and utility applications. Meters measure energy directly in 3-wire and
4-wire networks according to the principle of fast sampling of voltage and current signals.
A built-in microprocessor calculates active/reactive/apparent power and energy, current, voltage, frequency, power factor,
power angle and frequency (for each phase and total sum) from the measured signals. This smart meter can also perform
basic harmonic analysis (THDU, THDI). This enables quick overview of harmonic distortion either coming from a network
or generated by the load. Microprocessor also controls LCD, LED, IR communication and optional extensions.
A capacitive touch button on the front of the energy meter enables access to switch between measurements and settings
in the menu. Connecting terminals can be sealed up against non-authorised access with protection covers.
The meters are built to be fastened according to EN 60715 standard.

FIRST STEPS
Programming a three-phase electrical energy meter 7M.38.8.400.xxxx is very transparent and user friendly.
Numerous settings are organized in groups according to their functionality.
In this chapter you will nd basic programming steps:
- KEYBOARD NAVIGATION
- LCD USER INTERFACE
CALIBRATION AND SETTING PARAMETERS
FREEZE COUNTERS
KEYBOARD NAVIGATION
The capacitive touch (symbol below) is used for shifting between screens, for selecting the specic segment of the menu
and for conrming the settings. Press the capacitive touch (short-touch) to move forward between the screens. Long-touch
(approximately 3 seconds) is used to conrm the selection, to sett the next digit, or to enter the sub-menu. Very-long-touch
(approximately 5 seconds) considers the function ESC (during the parameter setting the screen goes back to the explicit
parameter in the other cases the LCD returns in the initial cycling mode).
If the screen backlight is o, the rst touch turns on the backlight, then the long-touch to view the main menu.
If the lock of the capacitive touch is available, to activate it, a very long-touch is needed.

After the electrical connection, the display shows an info screen (picture on top) for two seconds.
The following is holding page (default setting) of last observed measurement on the screen.
Measurements consist of energy counters and other actual measured values.
The MID approved meter shows a warning screen (picture on the right) Installation
Not set every 5 seconds if the installation of connection mode is not set yet.
Besides the holding page of measurement, one can enter the display menu structure by using a long touch. If the capacitive
touch is not pressed for more than 90 seconds, that specic measurement screen will be shown again.
This is also in case of a powerdown.
Cycling page function is a function that cycles measurements on the screen regarding the period that is dened in settings
(for more details see chapter Settings, Device settings, General settings, Display). If the capacitive touch is not pressed for
more than 90 seconds, the cycling of measurements automatically begines again. The explicit settings can be changed
through the Setting menu (for more details see chapter Display of device setting), Fi-MIS software or mobile app using NFC.
PLEASE NOTE
All settings that are performed can be subsequently changed via Fi-MIS by means of communication
PLEASE NOTE
The meter can be set to Test measuring mode which displays energy registers with better resolution.
The test mode is used for test purposes during type testing and test of meter constant during initial verication.
After power o meter automatically goes back to normal operation.
Page 16
User’s Manual 7M 15
CAPACITIVE TOUCH SELF CALIBRATION PROCESS
In a reported xed 64s interval the average, minimum and maximum value of the capacitive touch sensor is calculated.
If the conditions are stable (without interruptions) then the average value of the capacitive touch sensor is used as a reference
value.
If the new reference value deviates suciently from the permanently stored value, it is permanently saved.
Permanently stored value is used when the power is turned on.
ENERGY COUNTERS
There are two sets of energy registers – four non-resettable registers which can be assigned for active energy (MID approved),
reactive energy (national approval) or apparent energy (no approval).
The meter with MID approval should have at least one register with active energy measurement.
There are additional 16 energy registers which can be parameterised by the user regarding type of energy, active quadrants,
direction of counting and tari and they can also be resetted using MODBUS command or cap touch.
On the LCD up to two energy counters are displayed.
There is the lock sign for the xed legally relevant non-resettable counters, the counter designation, the sign of currently
active register, an additional code and the unit.
For the code the user can choose between the OBIS code or letter description code (the latter is the default). The 9-digit
numerical number shows the value of the energy. The decimal dot is xed and resolution is xed to 100 Wh. The screen is
displayed for the pre-set cyclic period.
PLEASE NOTE
In compliance with the MID directive, where the nal test is done before selling the products, it may happen that the MID
energy meters show a low energy consumption even if they are new.
This can only happen to relatively small percentage of meters for each production lot and the highest value should be
around 6 kWh for the Active Imported Energy
Page 17
User’s Manual 7M 16
Legally relevant non-resettable registers are designated with letters 1 to 4 after the lock sign, while legally non-relevant
resettable registers are designated with 01 to 16. The code is specied in table 4 and table 5.

to both import and export registers taking into accout each individual phase. It is applicable only in 4-wire connection.
Default value is the common three-phase 4-wire connection (3L+N) which enables also
– export evaluation as the sum of phases.
the message Installation not set is switched o.
In case 4-wire arithmetic mode with import-export evaluation for individual phases or 3-wire 2-system connection are chosen
the password DCBA has to be entered to allow the modication. In 3L-2I connection the phase measurements are blocked
on LCD while in 3L connection they are not automaticly blocked.
It is recommended to remove phase voltage and power measurements at Displayed measurement setting as these are not
relevant at 3-wire connection.

ERROR DISPLAY ON LCD
If error is detected Error display appears on LCD after each cycle for 5 seconds.
The rst two bits are the summary description of CRC errors.
The decimal value of rst 3 Bits (0 ...7) is displayed as Error.
The other bits are shown with 2 values:
- Data CRC – shows Parameter CRC details – decimal value (0...3f) of bits 8 to 13
- Code CRC – shows Firmware CRC details – decimal value (0 ...1f) of bits 3 to 7
CALIBRATION AND SETTING PARAMETERS
Calibration parameters can only be changed in production.
They cannot be changed by upgrade or dierent processes.
Special factory software is used to calibrate the parameters for current, voltage, and phase angle.
If these parameters were tenaciously or accidentally changed, an error type 1 is detected and Error 1 is shown on the LCD.
Calibration parameters are checked every 64 seconds.
The parameters related to energy measurement can only be changed if the MID key is unlocked.

APPENDICES
APPENDIX A: MODBUS COMMUNICATION PROTOCOL
Modbus protocol enables operation of device on Modbus networks. For 7M.38.8.400.XXXX\ with serial communication the
Modbus protocol enables multi drop communication via RS485 communication. Modbus protocol is a widely supported
open interconnect originally designed by Modicon.
The memory reference for input and holding registers is 30000 and 40000 respectively.
PLEASE NOTE
The Modbus table is subject to change without notice.
For the latest and complete Modbus table please visit FINDER S.p.A web page.
Communication operates on a master-slave basis where only one device (the master) can initiate transactions called ‘Requests’.
The other devices (slaves) respond by supplying the requested data to the master. This is called the ‘Request - Response Cycle’.
The master could send the MODBUS request to the slaves in two modes:
• Unicast mode, where the master sends the request to an individual slave. It returns a replay to the master after the request
is received and processed. A MODBUS transaction consists of two messages. Each slave should have an unique address.
• Broadcast mode, where the master sends a request to all slaves and an answer is never followed. All devices should accept
the broadcast request function. The Modbus address 0 is reserved to identify the broadcast request.
MASTER TO SLAVE REQUEST

SLAVE TO MASTER RESPONSE
Device addressDevice addressFunction Codenx8 bit data bytesError check
REQUEST
This Master to Slave transaction takes the form:
• Device address: master addressing a slave (Address 0 is used for the broadcast address, which all slave devices recognize)
• Function code e.g. 03 asks the slave to read its registers and respond with their contents
• Data bytes: tells the slave which register to start at and how many registers to read
RESPONSE
This Slave to Master transaction takes the form:
• Device address: to let the master know which slave is responding
• Function code: this is an echo of the request function code
• Data bytes: contains the data collected from the slave

REGISTER TABLE FOR THE ACTUAL MEASUREMENTS
The tables below represent the complete set of MODBUS register map. Register refresh frequency for actual measurement
from register 30105 to register 30190 is one second. Register refresh frequency for energy counters (from 30406 to 30441)
is 40 ms.
The registers from 30426 to 30441 (1000 x Energy Counter from 30406 to 30413 and from 30418 to 30425) represent the
same energy counters at 1000-times higher resolution.
This registers cam be read to calculate the energy dierence in the time interval more accurate.

APPENDIX B: MBUS
The M-BUS interface fully complies with M-BUS European standard EN13757-2. The entire communication
is ensured with 8 Data Bits, Even Parity, 1 Stop Bit and a Baud Rate from 300 to 9600 Bauds.
COMMUNICATION SETTINGS
Default communication settings are: 2400, 8, E, 1 primary address 0 and secondary address is set to serial number of device.
INITIALIZE MBUS SNK_NKE
This Short Telegram initializes the M-BUS 7M.38.8.400.XXXX.
The M-BUS 7M.38.8.400.XXXX conrms correct receipt by Single Character Acknowledgement (ACK = E5).
If the telegram was not correctly received the 7M.38.8.400.XXXX will not send an acknowledgement.
SELECT MBUS 7M.38.8.400.XXXX USING SECONDARY ADDRESS SND_UD
This Telegram enables to select M-BUS 7M.38.8.400.XXXX. The M-BUS 7M.38.8.400.XXXX conrms the correct receipt by ACK.
If the telegram has not been correctly received the M-BUS 7M.38.8.400.XXXX will not send an Acknowledgement.
After issue of the Single Character Acknowledgement the M-BUS 7M.38.8.400.XXXX is ready to transmit the entire Read-out
Data within 3 seconds from receiving the Telegram „Transmit Read-out Data“.
At the end of 3 seconds the M-BUS 7M.38.8.400.XXXX will switch back to normal mode.
TRANSMIT READOUT DATA VIA PRIMARY/SECONDARY ADDRESS REQ_UD2
This Short Telegram enables to select the M-BUS 7M.38.8.400.XXXX and to command it to transmit the Read-out Data
parameterized. The M-BUS 7M.38.8.400.XXXX conrms correct receipt by transmitting of the Read-out Data.
If the Short Telegram has not been received correctly; no Data will be transmitted by the M-BUS 7M.38.8.400.XXXX.
The Read-out Data are sent within 35 ms – 75 ms from receipt of the Short Telegram by the M-BUS Meter (fom more infomations
see section M-Bus telegrams).
SET BAUD RATE VIA PRIMARY/SECONDARY ADDRESS SND_UD
This telegram enables to set the desired Baud Rate. The M-BUS 7M.38.8.400.XXXX conrms the correct receipt by ACK.
If the telegram was not received correctly the M-BUS 7M.38.8.400.XXXX does not send an Acknowledgement.
The (ACK) is sent by the M-BUS 7M.38.8.400.XXXX in the Old Baud Rate. As soon as ACK is transmitted the M-BUS Meter
switches to the baud rate newly parameterized. If the 7M.38.8.400.XXXX now does not receive a new Telegram under the
new baud rate within a period of 30 seconds – 40 seconds, it automatically switches back to the old baud rate.
This is apt to prevent that a faulty setting of the baud rate may interrupt communication.
SET PRIMARY ADDRESS VIA PRIMARY/SECONDARY ADDRESS SND_UD
This Telegram enables to set a new Primary Address. The M-BUS 7M.38.8.400.XXXX conrms the correct receipt by ACK.
If the telegram has not been correctly received the M-BUS 7M.38.8.400.XXXX will not send an Acknowledgement.
SET SECONDARY ADDRESS VIA PRIMARY/SECONDARY ADDRESS SND_UD
This Telegram enables to set a new Secondary Address. The M-BUS 7M.38.8.400.XXXX conrms the correct receipt by ACK.
If the telegram has not been correctly received the M-BUS 7M.38.8.400.XXXX will not send an Acknowledgement.
Secondary Address (UD) consists of:
Identication Number: 00000000 – 99999999 8-digit Secondary Address number
RESET, RESTART MBUS MC350 VIA PRIMARY/SECONDARY ADDRESS SND_UD
This Telegram reset/restarts M-BUS MC350. The M-BUS 7M.38.8.400.XXXX conrms correct receipt by ACK.
If the telegram was not correctly received the M-BUS 7M.38.8.400.XXXX will not send an acknowledgement.
