EMM.630(M)CT-MID (1A of 5A CT) and
EMM.630MCT-RC (Rogowski coils)
The EMM.630 (M)CT is an advanced 3 phase
energy monitor with direct connection to the
mains for measuring reference voltages and
3 connection for linking the current
transformers 1A or 5A CT or Rogowski coils
(EMM.630 MCT-RC) with which consumers
can be measured >100A. The configuration
of the meter is done via the touch keys on
the front panel and the LCD display. The bi-
directional measurement measures
consumption on mono, 3x230V or 3x380V+N
power supplies. Both active and reactive power are measured. The
readout of the consumption values can be done via the display or on the
linked web server. The module is packed in a 4 module wide DIN rail
housing. In addition to an RS485 connection, this energy meter also has 2
pulse outputs, of which 1 is configurable.
1. Connect:
Attention 1: To avoid voltage surge: first connect coil conductors to the
meter, only then clip coil around current conductors !! Install the power coil
only by a qualified electrician !!! Wear safety goggles during every operation
with the coils !!!
Attention 2: With the EMM.630 CT-MID, the type of coil can only be
entered once, see point 2. Configuration on display
Attention 3: After connecting the coils via display key "P" polarity check,
if negative power(Watt) or negative PF then open and turn coil, unless
there would be injection by solar panels!
Attention 4: The measured reference voltage and the measured current
must be at the same stage: ALWAYS test with voltmeter : Voltage
between conductor reference voltage and conductor flow pool must be
ZERO, otherwise you have a wrong measurement!! Here you can possibly
use the voltage drain terminals type UAD (see website)
EMM.630 (M)CT: Mono-phase connection
On display: set as mono phase: SYS 1P2
Reference voltage: Neuter on Clamp 1; Phase on Clip 4
Flow coil: Keep flow arrow on coil, arrow points to Users! Black
conductor(=GND) on Clip 19; White conductor on Clip 20
Power voltage module: Neuter on Clamp 6,Phase on Clamp 5
Note: by-loop-Clamp to next meter Clamp 7= Clamp 5; Clip 8= Clamp6

2: Configuration on the display:
This module is partly pre-configured and only needs to be entered:
 a UNIQUE Modbus address, number between 1... 247
 the type of power supply mono,3x230V,3x380V+N, standard at
3x380+N
 the type of coil: be careful, this can only be done once and cannot
be adjusted afterwards!!!
How to get into SETUP:
 (watch video tutorial) https://www.2-wire.net/en/product/3f-
energy-meter-ct-mid-modbus-emm-630-ct/)
Push the bottom button 4 (enter→)until PASS 0000 appears, fill in default
password PAS 1000 by pressing the button 2 (M↑) to 1, briefly press button
4 (enter) for next number or press enter for a long time to move to next
setting. Go through button 3 (P√) through the set values and adjust the
necessary Modbus values. Briefly press button 1 (U/I ←)) to leave menu.
Modbus parameters to be set: 9600 8N1
 Modbus address : Id001... Id247
 Baudrate: b 9600
 Parity: Prty n (parity none)
 Data: 8 bit
 Stopbit: 1
Secondary current of the coil 1Ampere or 5Ampere: SET
Ct2 5 At the EMM.630CT-MID this can only be set
once!!
Multiplication factor = primary/ to secondary flow
strength of the coil, E.g. 100A/5A=20: Ct rATE 0020
With the EMM.630CT-MID this can only be set once!
In case Rogowski: CT1 should be set to 1kA, in the
EMM.630 MCT-RC meter you can still change settings
afterwards
ATTENTION:
1. The values SET Pt2 400 and Pt rAtE 0001 are
for high voltage and can only be adjusted once.
Leave it on DEFAULT! !
2. The backlight of the display can be set to
0/5/10/30/60/120.
0 stands for continuous, 5/10/30/60/120
means switch off after the set period . Here
better choose 5/10/30 to increase the service
life.
3: Configuration in the web server
In the web server, go to /configuration/modules:

cabling check,...)
4. Read values on the display
There are 4 touch buttons by pushing on this momentarily you can read the
following readings:
Button1 U/I (voltage/currents): voltages between phase Neuter Volt→ flow
per phase in Ampere→ Harmonic on voltage between phase and neuter THD
in %→ Harmonic on current THD in %→
Button 2 M (frequency, PF, peak): frequency and power factor→ power
factor per phase → maximum flow per phase with set sample me aer
reset→ maximum total power set sample me aer reset Button
3 P (capabilities): current active power per phase in kW→ current reacve
power per phase in kVar→ current VA per phase in kVA→ total power in kW,
KVar, kVA
Button 4 E (energy consumption meter reading)*: meter reading total
active consumption in kWh→ meter posion total reacve consumpon in
kVarh→ meter posion import acve consumpon in kWh → meter posion
export active consumption in kW → meter posion import acve
consumption in kVarh → meter state export acve consumpon in kVarh →
*beware meter reading on 2 lines as 1 line: 0001 04.80 kWh=104.80kWh
5. What values are logged.
MEMo logs every 60 seconds:
 Total active consumption over the 3 phases:
o Meter mode import in kWh
o Meter mode export in kWh
 By phase:
o Tension in Volt
o Power in Ampère
o Power in Watt
o Power factor
o Reactive capability VAR
6. General note:
 Import consumption over the 3 phases, in the html chart only with
1 hour resolution, is calculated on the basis of difference between
start and end counter position and the result you see in the web
server below the chart of phase 1 (Modbus sub-address0). Export
consumption can be found in the web server under phase 2
(Modbus sub-address 1),see FAQ on 2-wire.be
 The current counter positions import and export can be read in
the web server (light green values) by pressing 'AUTO REFRESH'.
 Via button E on the display is ToTal Energy = Import +Export in
kWh
 3x380V NEUTERLESS: connect as 3x230V and set as 3P3
 Visualization of the channels for the customer : see WS.502 web
server
 Because the web server cannot show
negative graphs, the Energy meter for solar
panels must be connected in the direction of
the current.
 If current power is at 0 in the web server
then check flow direction coils via display
 Rinsing flow direction is wrong if PF or power
on the display is negative, Never swap wires
from coils around current feeder but open and
turn the coil to avoid power surge!!!
 In the case of 3x230Volt, current power Phase 2 is always shown
as zero in the web server because this calculated power is
negative and the web server does not show any negative values.
 Flow-rinse guides may be extended a few meters but with at least
the same section
 The comprehensive (English) manual with all technical
specifications, detailed configuration, Modbus registers is
available through our website www.2-wire.net
