1 General Description
The SMC 133 is specially designed for monitoring of energy and power quality in advanced power systems and
smart grids. It is intended to be used mostly for DIN rail mounting. This display-less design with multiple
communication options is suitable for a wide spectrum of automation tasks in modern buildings, distributed
power generation, remote supervision of the infrastructure and also remote load management. Two different
user interfaces are offered - SMC 133 D with a small embedded color display on the front panel for simple local
value reading and an unobtrusive SMC 133 without display with limited ability for for hostile user interaction.
To protect the actual setup and collected data each instrument can be locked by a custom pin. It uses standard
RS-485 serial line for communication with remote control systems. Optionally it can be equipped with other
communication peripherals such as Ethernet, USB, WiFi, ZigBee (custom options).
It is equipped with three voltage input and three current inputs. The default current input option X/5A
uses common X/5A or X/1A current transformers. The instrument can be supplied with inputs customized for
current transformers with X/100 mA ratio,
Warning! The X/100mA, options are specially designed to be used only in combination with provided
external current sensors which are supported with the respective option.
The SMC 133 is available in several configurations according to the customer requirements1. See the ordering
scheme on figure 1.

figure 4). It has to be located left to the instrument and easily reachable by the operator. The circuit breaking
device must be identified as the equipment power disconnection switch. A circuit breaker of the nominal value
1Ais a convenient circuit breaking device. Its function and position has to be clearly identified (symbols ‘0’
and ‘I’ acc. to IEC EN 61010-1). Internal power supply is galvanically isolated from internal circuits.
2.3.2 Measured voltage
The measured voltages are connected to the terminals L1, L2 and L3. Connect the neutral wire to the terminal
N. With delta or Aaron connections terminal N remains unused. Voltage measurement inputs are connected
with internal circuits over high impedance.
It is suitable to protect the measured voltage lines for example with 1A fuses of the required rating. Measured
voltages can also be connected via instrument voltage transformers. A connection cable maximum cross section
area is 2.5mm2for voltage terminals.
2.3.3 Measured currents
The instruments are designed for indirect current measurement via external CT only. Proper current signal
polarity (S1 or S2 terminals, k or l in the older notation) must be observed. You can check the polarity by the
sign of phase active powers on the instrument display, its web pages or in the ENVIS.Daq application.
X/5A current input option The current signals from 5A or 1A instrument current transformers must be con-
nected to the terminal pairs I11, I12, I21, I22, I31, I32 with a cable of maximum cross section area 2.5mm2and
a maximum length of 3 m.
X/100mA current input option The supplied current transformers (which are standard accessory) must be
clamped on measured wires with proper isolation and interconnected with corresponding terminal pairs I11,
I12, I21, I22, I31, I32 using a twisted-pair cable of maximum length of 3 m. The secondary winding of the
transformers is led to the screw terminals. The S1, S2 (or ”K“/”L“ and ”k“/”l“) orientation is marked on the CT
guide groove. A connection cable maximum cross section area is 1.5mm2.
Warning !: Connection of the common X/5A, X/1A or another unsupported current transformers to an
instrument with X/100mA option is strictly forbidden !!! The instrument can be seriously damaged!
2.3.4 Communication peripherals
All peripherals stated below are galvanically isolated from the rest of the instrument and from each other.
Ethernet interface (optional) 100 Mbit Ethernet interface with RJ-45 connector (100Base-TX) labeled as ETH
is situated on a top panel of the device. Ethernet interface can be used as substitution for the primary RS-485
for connection of the device to LAN and for easy connection of remote control PC.
RS-485 serial line serves usually as a remote communication for reading of actual data, archive downloading
and device configuration. Serial RS-485 line uses terminals A+, B- with shielding at terminal Gof COM1 block
(fig. 6). The end point of the communication line must be properly terminated with ˜120Ωresistor.

Figure 6: Typical wiring of the RS-485 communication line terminals in SMC 133 .
USB (optional) communication port for USB slave is located on the front panel. This communication port is
intended for easy local configuration and fast download of archived data to the local PC. Use the supplied USB
cable only (USB-A/mini). SMC 133 is a USB 2.0 slave device. For correct operation it needs a driver installed
in your operating system (see the ENVIS user guide for more info).
2.3.5 Inputs and outputs
Instrument provides two separate universal I/O ports with terminals C1, D1 and C2, D2. Each DI/O port can
be used individually as an input or an output function. For a correct operation of the I/O it is necessary to use
an external power supply with nominal voltage 12 to 24 VDC. Appropriate polarity of supply voltage for input
resp. output function must be kept.
Warning! Digital I/Os are unipolar. Right polarity must be kept for a proper operation of the terminal.
Incorrectly connected external power supply can damage the instrument.
DI/O as a digital input DI is connected to the selected I/O terminal (D1 or D2) and a common terminal (C1
or C2) with external power supply in the following way: the current flows from positive terminal of the supply
through the external input contact to a DI terminal (D1 or D2) and than from the common terminal (C1 or C2)
back to the negative terminal of the external power supply.
DI/O as a digital output DO is connected to the selected I/O terminal (D1 or D2) and a common terminal (C1
or C2) with external power supply in the following way: the current flows from positive terminal of the supply to
the C1 or C2 terminal and from a DI terminal (D1 or D2) through the controlled load to the negative terminal
of the supply. If an I/O port is used as an output (its behavior is controlled by an internal logic function) the
instrument also indicates its activation with the respective input register.
2.4 Downloading data to PC

2.5 Energy meter readings
SMC 133 has an embedded three phase, four-quadrant energy meter with automatic meter reading functions and
multiple programmable tariffs (Time-of-Use, TOU). The instrument registers active energy (EP, EP+, EP-) and
reactive energy (EQL, EQC or EQC+, EQC-, EQL+, EQL-). According to the configuration of meter readings
are shuffled to the respective tariffs. It automatically provides summaries per phase. For star connections and
single phase measurements it can also register energy for each phase separately.
Meter data readings can be downloaded and analyzed in ENVIS or via the standard ModBus protool in any
other system.
