2. Installation
2.1 Meaning of the symbols used on instrument
Warning – read operating manual !
AC – alternating voltage
DC – direct voltage
CE marking guarantees compliance with the European directives and regulations
The instrument must not be disposed of in the normal unsorted municipal waste
stream
Basic insulation instrument (protection class I)
Double or reinforced insulation instrument (protection class II)
2.2 Physical
The instrument is built in a plastic box to be installed in a distribution board panel. As a rule, the panel
is a part of a switchboard door - then the installation must be such that the switchboard door can be
closed under all conditions of use. In any case, it must be ensured that only the front panel of the
instrument is accessible to laypersons. Therefore, if the switchgear is located in an area accessible to
laypersons, the switchgear door or panel must only be opened by means of a tool, or the door must be
locked.

SMY133-SMY134-SMP133 Operating Manual
The instrument’s position must be fixed with locks.
Natural air circulation should be provided inside the distribution board cabinet and in the instrument’s
neighbourhood no other instrumentation should be installed.
Fig. 2.1b : Space around the Instrument
Especially underneath the instrument, no other instrumentation that is source of heat should be
installed or the temperature value measured may be false.
2.3 Instrument onnection
2.3.1 Safety Grounding (SMP133 only)
As the SMP133 is safety class I type instrument, it must be grounded.
The instrument is equipped with the faston-type terminal 6.3 x 0.8 mm, marked (sometimes
referenced as PE-terminal).Corresponding crimp-type receptacle is delivered with the instrument as
standard accessory.
Fig. 2.2 : SMP 133 Grounding
The terminal must be connected with the PE (or PEN) protection ground conductor (bare or with
green/yellow coloured insulation).
Recommended wire type : H07V-U (CY)
Recommended minimum conductor cross-section : 2.5 mm2
Maximum conductor cross-section : 4 mm2
9

SMY133-SMY134-SMP133 Operating Manual
For safet reasons, the instrument must be grounded before connection of other signals!
2.3.2 Power Supply
The supply voltage (in range according technical specifications) connects to terminals AV1 (No. 9) and
AV2 (10) via a disconnecting device (switch – see wiring diagram). It must be located at the
instrument’s proximity and easily accessible by the operator. The disconnecting device must be
marked as such. A two-pole circuit breaker with the C-type tripping characteristics rated at 1A makes a
suitable disconnecting device. Its function and working positions, however, must be clearly marked.
In case of DC supply voltage the polarity of connection is generally free, but for maximum
electromagnetic compatibility the grounded pole should be connected to the terminal AV2.
Recommended wire type : H07V-U (CY)
Recommended minimum conductor cross-section : 1.5 mm2
Maximum conductor cross-section : 2.5 mm2
2.3.3 Measured Voltages
The phase voltages measured are connected to terminals U1 (12), U2 (13), U3 (14), the common
terminal to connect to the neutral wire is identified as N (11; it stays free at delta- (3-D) and Aron- (A)
connections). It is suitable to protect the voltage lines measured for example with 1A fuses. Measured
voltages can also be connected via instrument voltage transformers.
Recommended wire type : H07V-U (CY)
Recommended minimum conductor cross-section : 1.5 mm2
Maximum conductor cross-section : 2.5 mm2
2.3.4 Measured urrents
The instruments are designed for indirect current measurement via external CTs only. Proper current
signal polarity (S1 & S2 terminals) must be observed. You can check the polarity by the sign of phase
active powers on the instrument display (in case of energy transfer direction is known, of course).
It is necessary to set the CT-ratio – see example below.
The I2 terminals stay free in case of the Aron (A) connection.
2.3.4.1 urrent Type urrent Inputs Instruments ( Models „X/5A“,
„X/100mA“ )
The current signals from 5A or 1A (or 0.1A for the „X/100mA“ models) instrument current transformers
must be connected to the terminal pairs I11, I12, I21, I22, I31, I32 (No. 1 ÷ 6). At the “134” model, you
can connect the 4th current signal too to the terminals I41, I42 (No. 7 ÷ 8).
Recommended wire type: H05V-U (CY)
Recommended minimum conductor cross-section :
•“X/5A” instruments : 2.5 mm2
•“X/100mA” instruments : 0.75 mm2
Maximum conductor cross-section : 2.5 mm2
10

SMY133-SMY134-SMP133 Operating Manual
2.3.4.2 Voltage Type urrent Inputs Instruments ( Models
„X/333mV“ )
The instruments are equipped with separate connectors for particular measuring current input. Each
connector has three terminals. Function of the terminals is described in following table :
“X/333mV“ Models Current Inputs Connection
terminal No. signal
62 SI1 … signal corresponding to I1 current (in phase L1), CT terminal “S1”
65 SI2 … I2-S1 (phase L2)
68 SI3 … I3-S1 (phase L3)
63, 66, 69 SG …common pole of the I1 ÷I3 signals (CT terminals “S2”) and negative pole of the
5V built-in auxiliary power supply for current sensors (the terminals are
interconnected)
61, 64, 67 SP... positive pole of the 5V built-in auxiliary power supply for current sensors (the
terminals are interconnected)
The instruments are designed for cooperation with current transformers with output nominal voltage of
333 millivolts. They can be also used with flexible current sensors (Rogowski coils) with embedded
integrator of appropriate voltage output signal.
The CTs must be connected with two-wire twisted cable. Again, proper current signal polarity (CT
secondary terminals S1, S2) must be observed.
Recommended wire type : twisted pair, for example KU03G24 ( Nexans )
Recommended minimum conductor cross-section: 0.2 mm2
Maximum conductor cross-section: 1.5 mm2
Maximum length of the cable is 3 metres !
The flexible current sensors with embedded integrator usually require a power supply. For such
purpose the instruments are equipped with auxiliary power supply 5V. Maximum load of each sensor
connected is 20 mA.
Connection of standard CTs with 5A or 1A nominal output current to the „X/333mV“
instruments s forbidden !!! Otherwise the instrument can be damaged !!!
2.3.5 Other Inputs/Outputs
Connection of residual current inputs, other inputs, outputs and communication links are described in
appropriate chapters further below.

3. ommissioning
3.1 Setup
When switching on the power supply, the instrument will display manufacturer's logo for short time and
after that, one of actual data screen - for example the line-to-neutral voltages one - is displayed :
At this moment it is necessary to set instrument parameters that are essential for proper instrument
measurement (so called Installation group) :
•mode of connection ( direct measuring or via metering voltage transformers )
•type of connection ( star, delta, Aron )
•ratio of CTs, VTs and their multipliers (if used)
•nominal voltage UNOM and nominal frequency fNOM
•INOM, PNOM (not mandatory, but recommended)
3.1.1 Measured Electrical Quantities Installation Setup
For the proper data evaluation it is necessary to set all of the Installation Setting group
parameters.
•onnection Mode determines if voltage signals are connected directly or if voltage
transformers are used.
•onnection Type needs to be set according network configuration – wye (or star, Y ) or
delta ( D , if neutral voltage potential not connected ). Usually, all of three phases are
connected so choose 3-Y or 3-D. For Aron connection set 3-A. For single-phase connection,
set 1-Y.
•T ( TN, TR M) - ratios must be specified, in case of “via VT” connection mode VT-ratio too.
The T is valid for currents I1, I2 and I3. If the fourth current input or residual current inputs
are used, appropriate ratios TN / TR M must be set too.
CT ratios can be set in form either …/ 5A or …/ 1A or …/ 333mV.
The VT-ratio must be set in form Nominal primar voltage / Nominal secondar voltage . For
higher primary voltage values the U-multiplier must be used too.
•I- and U-Multipliers - You can modify any CT- / VT-ratio with this parameters. For example,
to get better precision when using overweighted CTs, you can apply more windings of
measured wire through the transformer. Then you must set the multiplier. For example, for 2
windings applied, set the multiplier to 1/2 = 0.5 .
For standard connection with 1 winding, the multiplier must be set to 1.
The TN and TR M ratios have their extra IN – and IR M–Multipliers.
12

SMY133-SMY134-SMP133 Operating Manual
Instead the IRCM–multiplier, the 0/20mA or the 4/20mA RCT- type can be set – see the RCM
chapter below.
•Nominal Frequency fNOM - the parameter must be set in compliance with the measurement
network nominal frequency to either 50 or 60 Hz, optionally to „DC-500“ (= Fixscan mode).
• Nominal Voltage UNOM, Nominal urrent INOM, Nominal Power PNOM - For the presentation
of quantities in percent of nominal value, alarms operation, voltage events detection and
other functions it is necessary to enter also the nominal ( primary ) voltage UNOM, nominal
current INOM and nominal apparent three-phase power (input power) of the connected load
PNOM ( in units of kVA ) Although the correct setup has no effect on measuring operation of the
instrument, it is strongly recommended to set at least the UNOM correctly.
Correct setting of the INOM and the PNOM is not critical, it influences percentage representation
of powers and currents and statistical processing of measuring in the software only. If
measured network node rating is not defined, we recommend to set their values, for example,
to the nominal power of source transformer or to the maximum supposed power estimated
according current transformers ratio, etc.
The UNOM is displayed in form of phase/line voltage.
3.1.1.1 Setup Example
Following example explains how to adjust the CT ratio :
Assuming that the conversion of used CT for inputs of current L1 to L3 is 750/5 A. To edit the
parameters, press the , navigate to the Menu-Settings with the buttons
and and then choose it with the . In the Setting window choose Setting-
Installation option. The Setting-Installation window appears.
In the window navigate down to the current transformer ratio parameter ( CT ) and choose with the
.
Now you can type new value of the parameter : with the you can move from a digit to
another one and to set each digit to target value using the and . At the end press
the and the parameter is set.
You can set other parameters in the same way.
After all of the parameters of the group correctly set, return back to an actual data screen with the
(escape) button and confirm saving of changes with the .
13

SMY133-SMY134-SMP133 Operating Manual
Now you can browse through displayed actual values with the and and check if
they correspond with reality.
For proper CT connection checking, ou can use phasor diagram screen.
After measured quantities checked, other parameters (of RTC, averaging, remote communication etc.)
can be set .

4. Detailed Description
4.1 Basic Functions
The instruments evaluate all of usual electric quantities like line-to-line and phase voltages, currents,
active, reactive and apparent powers, power factors, voltage and current THDs and harmonic
components, active and reactive energy, average power maximums, frequency etc. Furthermore,
temperature is measured with built-in sensor. Optionally, the second temperature can be measured
with an external Pt100 sensor at appropriate instrument models.
The instruments are fitted with inputs for connection of three voltage signals, three or four current
signals (for connection of external CTs with either 5/1 AAC or 0.1 AAC or 333 mVAC nominal secondary
signal) and separate AC/DC power supply input. They can be used in both low and high voltage power
grids.
The instruments feature three-rate tariff electricity meter with four-quadrant counters for both active
and reactive energies and maximum average active power ( maximum demand ) registration.
Advanced models store all results for actual and last month too and a separate archive dedicated for
automated meter readings can record actual status in preselected intervals.
Certain models can be used for residual current monitoring too.
The instruments are equipped with battery backuped real-time circuit (RTC) and high capacity „Flash"
type memory for measured data and events recording.
The USB 2.0 communication link can be used for the instrument adjusting and recorded data transfer.
For remote access, optional RS-485 or Ethernet or M-Bus communication interface is available. The
instruments with Ethernet interface have embedded webserver.
Basic specifications of the instrument can be set up by using the inbuilt keyboard and the display. With
the ENVIS program supplied as standard you can, via any of communication link, adjust the
instrument and transfer recorded data. In addition to the instrument adjustment, ENVIS program
allows you to display, view and archive the measured courses in the graphic form, as well as a
number of other features.
4.2 Manipulation and Setting
4.2.1 Data Area – Status Bar - Toolbar
Instrument's screen consists of two parts : a data area and a status bar / toolbar area.

4.2.11 Instrument Settings ( Parameters )
In this group most of presetable parameters can be viewed and edited. Other parameters
can be accessed via communication link using the ENVIS-DAQ program only.
If any of setting window is viewed, an instrument automatically reswitches to actual data display during
an approx. 1 minute if no manipulation with buttons is carried out.
Following chapters explain the meaning of particular groups of parameters.
4.2.11.1 Display Setting
•ontrast … Can be set in range 0 – 100%
•Brightness … The set level of brightness is activated whenever any button is pushed. If no
manipulation with buttons for approx. 5 minutes, the brightness is automatically decreased in
order to decrease instrument power dissipation and to spare display lifetime.
•Language … In addition to the basic English version, other language versions can also be
set.
•Display refresh cycle … Actual values refresh period. For details see chapter Displa
Actual Values Evaluation and Aggregation.
•Display Resolution … Actual & average data groups format be set to 3 or 4 significant
figures.
4.2.11.2 Installation Setting

above ( the Commissioning part ).
4.2.11.3 Remote ommunication Setting
Communication parameters for various interface types differ from each other :
OM (RS-485) interface :
•ommunication Address
•ommunication Rate …in Bauds (Bd)
•Data Bits … including parity bits! Set to 8 for KMB-protocol; set to 9 when parity bit is used
(Modbus-protocol, for example)
•Parity …none/even/odd
•Stop Bits … set to 1 (usually)
Ethernet interface :
•DH P ... activation of dynamic IP-address allocation
•IP Address …internet protocol address
•Subnet Mask …subnet mask
•Default Gateway …default gateway
•KMB-port … communication port used for KMB protocol communication (2101 as default)
•Web-port … communication port used for webserver communication (80)
•Modbus-port … communication port used for Modbus protocol communication (502)
Nex information can be found in chapter Computer Controlled Operation below.
4.2.11.4 lock Setting
•Date & Time … Local date and time
•Time Zone … The time zone should be set according location of an instrument
during installation. Correct setting is essential for proper local time interpretation.

SMY133-SMY134-SMP133 Operating Manual
•Daylight Saving … This option controls automatic winter/summer local time
switching
•Time Synchronization … As the built-in real time circuit has limited accuracy while free
running, with this option it is possible to keep the RTC time in synchronism with an external
precise time source. The RTC can be synchronized by :
•Pulse Per Second / Minute (PPS / PPM ) … A digital input is used for time
synchronization from an external source at this case. The instrument sets the RTC
to the nearest second or minute as soon as a synchronization pulse is detected.
Second-, Minute-, quarter-hour- or hour- synchronization pulses are accepted.
•NMEA Message ...If an instrument is equipped with the RS-485 remote
communication interface an external ( usually GPS-based ) time receiver can be
connected to. The receiver must be set to transmit the “ZDA”- or “RMC ”-message
(NMEA 0183 protocol). The communication interface must be set appropriately
(usually 4800 Bd, 8 bits, 1 stopbit).
•NTP Server ...The option can be used if an instrument is equipped with the Ethernet
communication link and a NTP-server is available in the network. Set IP-adress of
the server. Then time synchonization is performed every hour.
•Network Frequency … For this option, the nominal frequency fNOM parameter must
be set properly. Otherwise the synchronization will not work.
Warning : When editing clock parameters, it must be taken into account that internal data
archives are affected : when changing the date or time, all archives are cleared !
4.2.11.5 Average Values Processing Setting

•Method … Method of the signal evaluation can be set either to Filter or in compliance with
the IEC61000-4-30 standard
•fR … frequency of the ripple control signal in Hz
•UR unit … ripple control voltage unit : either V or percent of UNOM
•UR threshold (UR TR) … minimum signal level to be recognized as „pulse“. Relevant for
telegram detection, signal below the threshold is recognized as „gap“.
