SMY133-SMY134-SMP133 Operating Manual
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
