✧ Follow all advice instructions to prevent death or severe injury.

WARNING

Warning means that death or severe injury can occur if the appropriate safety measures are not taken.

✧ Follow all advice instructions to prevent death or severe injury.

CAUTION

Caution means that minor or moderate injury can occur if the appropriate safety measures are not taken.

✧ Follow all advice instructions to prevent minor injury.

NOTICE

Notice means that damage to property can occur if the appropriate safety measures are not taken.

✧ Follow all advice instructions to prevent damage to property.

NOTE

is important information about the product, the handling of the product, or the part of the documentation in
question to which special attention must be paid.

Personnel Qualified in Electrical Engineering

Only qualified electrical engineering personnel may commission and operate the equipment (module, device)
described in this document. Qualified electrical engineering personnel in the sense of this manual are people
who can demonstrate technical qualifications as electrical technicians. These persons may commission, iso­late, ground, and label devices, systems and circuits according to the standards of safety engineering.

Use as Prescribed

The equipment (device, module) must not be used for any other purposes than those described in the Catalog
and the Technical Description. If it is used together with third-party devices and components, these must be
recommended or approved by Siemens.

If the device is not used in accordance with the Product Information and this manual, the scheduled protection
is impaired.

Problem-free and safe operation of the product depends on the following:

• Proper transport

• Proper storage, setup, and installation

• Proper operation and maintenance

When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper ac­tion is not taken, death, severe injury, or property damage can result.

• The equipment must be grounded at the grounding terminal before any connections are made.

• All circuit components connected to the power supply may be subject to dangerous voltage.

• Hazardous voltages may be present in equipment even after the supply voltage has been disconnected
(capacitors can still be charged).

• Equipment with exposed current transformer circuits must not be operated. Prior to disconnecting the
equipment, ensure that the current transformer circuits are short-circuited.

• The limit values stated in the document may not be exceeded. This must also be considered during testing
and commissioning.

Application

The SICAM Measurement and Monitoring Unit (MMU) is capable of measuring electrical quantities (e.g. alter­nating current, alternating voltage) in power-supply systems. Transmission of quantities to the control center
can take place e.g. directly with IEC 60870-5-104 protocol. The device with protection class IP20 is used in 1­phase systems, in 3-wire and 4-wire systems (with neutral conductor). It is mainly applied by power utilities but
also in other industrial and commercial sectors.

The measurements are obtained from the alternating quantities of current and voltage supplied to the AC in­puts. Without using external voltage and current transformers, the device can process rated input AC voltages
up to V
currents up to a maximum of 5 A.

Depending on the device type, the input circuits for voltage measurement are either designed as voltage divid­ers or they are galvanically isolated. Devices with galvanic isolation can be used without voltage transformers
in the power systems IT, TT and TN. Devices with a voltage divider can also be used in these power systems;
for IT power systems, however, an upstream voltage transformer is required.

After conversion via the Ethernet interface, the output values can be transferred as digital data to automation
systems or other systems.

T o add 6 binary inputs and 6 binary outputs to the SICAM MMU, a SICAM I/O Unit 7XV5673 can be connected
to the Ethernet interface. The SICAM I/O Unit 7XV5673 can be connected either directly via the Ethernet switch
of the SICAM I/O Unit or via an external switch.

The integrated web server can be used to set the parameters and display the measured values on HTML pages
from the connected PC or notebook.

Measurands

The following measurands can be recorded or calculated from the measured quantities:

• Alternating voltage and alternating current

• Unbalanced of alternating voltage and alternating current

• Active, reactive and apparent power

• Active, reactive and apparent energy

• Voltage harmonics and current harmonics

• Power frequency

• Phase angle

• Angle between the phase-ground voltages a-b and a-c

• Power factor and active power factor

For detailed information on measurands and measured values, see chapter 4.1 and 4.2 and the technical data
in Section 13.1.

Communication

T o communicate with the control center and other process automation equipment, the device features an Ether­net interface.

Ethernet supports the device parameterization, the transmission of measured data, counter values and indica­tions and the time synchronization via NTP. The communication protocols are HTTP and Modbus TCP or
IEC 60870-5-104. At use of the protocol IEC 60870-5-104 two redundancy methods are supported.

Time Synchronization

During operation SICAM MMU needs the date and time for all time-relevant processes. This ensures that a
common time basis exists when communicating with peripheral devices and enables time stamping of the pro­cess data. The following types of time synchronization can be executed:

• External time synchronization via Ethernet NTP (preferred)

• Internal time synchronization via RTC (if external time synchronization is not available)

Parameterization

No special software is needed for parameterization. You can set the parameters from your computer via HTML
pages and a web browser. Internet Explorer 6 (or higher) is necessary for this purpose.

the cover of the battery compartment there is a labeling strip for the configurable LEDs H1/H2 and a battery
symbol that indicates the po l a ri ty. Th e l a be l i s al so located on the top side and provides among other informa­tion the most important rated data of the device. A lithium battery is located under the removable cover of the
battery compartment.

The terminals for connecting all inputs and outputs, for the supply voltage and the protective grounding are lo­cated on the terminal side. The number, type and position of the terminals differs according to device version
and is described in detail in chapter 5.3.

The snap-in unit is mounted in the center of the DIN rail side. The IP Addr. push-button is located in the lower
right corner of the DIN rail side. Pressing it (> 3 s) activates the factory-set default IP address. The default IP
address and the default subnet mask are imprinted on the side panel.
