Statemant of Conformity
Qualified personnel
Commissioning and operation of the equipment (module, device) described in this manual must
be performed by qualified personnel only. As used in the safety notes contained in this manual,
qualified personnel are those persons who are authorized to commission, release, ground, and
tag devices, systems and electrical circuits in accordance with the safety standards.
Use as prescribed
The equipment (device, module) must not be used for any other purposes than those described
in the Catalogue and the Technical Description. If it is used together with third party devices and
components, these must be recommended or approved by Siemens.
Correct and safe operation of the product requires adequate transportation, storage, installation,
and mounting as well as appropriate use and maintenance.
During operation of electrical equipment, it is unavoidable that certain parts of this equipment will
carry dangerous voltages. Severe injury or damage to property can occur if the appropriate
measures are not taken:
•Before making any connections at all, ground the equipment at the PE terminal.
•Hazardous voltages can be present on all switching components connected to the power
supply.
•Even after the supply voltage has been disconnected, hazardous voltages can still be
present in the equipment (capacitor storage).
•Equipment with current transformer circuits must not be operated while open.
•The limit values indicated in the manual must not be exceeded; that also applies to testing
and commissioning.
This product complies with the directive of the Council of the European Communities
on the approximation of the laws of the Member States relating to electromagnetic
compatibility (EMC Council Directive 2004/108/EC) and concerning electrical
equipment for use within specified voltage limits (Low-voltage Directive 2006/95/EC).
This conformity has been established by means of tests conducted by Siemens AG
according to the Council Directive in agreement with the generic standards EN 61000-
6-2 and EN 61000-6-4 for the EMC directives, and with the standard EN 61010-1 for
the low-voltage directive.
The device has been designed and produced for industrial use.
The product conforms to the standards IEC 60688, EN 60688 or DIN EN 60688.

1.1 Application and Mode of Operation
12 Power Meter SICAM P 7KG7750/55, Manual
E50417-B1076-C340-A6, Edition 09.2013
1.1 Application and Mode of Operation
Range of Application
The Power Meter SICAM P is capable of recording several different power system measure-
ments. In addition, the SICAM P is designed to be utilized in a number of different industries.
The display of measured quantities can be easily configured to the specific requirements of the
user.
Network linking is possible with the integral RS485 port equipped with the standard PROFIBUS
DP-V1,ModbusRTU/ASCIIorIEC 60870-5-103protocolwhichprovide forindication, evaluation
and processing of several SICAM P measurements at a central master station.
Mode of Operation
Input voltages and currents are sampled for calculation of the corresponding RMS values. All
measurementsderivedfromsampledvaluesarecalculatedbya processor. Measuredquantities
can be displayed on the screens and/or transmitted via the serial interface.
With the SICAM P, it is possible to program limit value groups for various measured quantities
toactivatelimit violationswhenthe valueofa specificmeasuredquantityexceedsa programmed
threshold. In addition, it is possible use logical elements (AND, OR) to combine two or more mea-
sured quantities for the purpose of generating a limit violation. Limit violations are counted, indi-
cated on the screen and/or utilized to operate the binary output contacts. The oscilloscope may
be triggered via a limit violation as well.
All measured quantities can be displayed on the SICAM P screens as required by the user. Up
to 20 screens can be selected with the front keys. The number, type, content and sequence of
the screens are configurable. SICAM P is delivered with pre-programmed default settings.
A status line displayed in the measured value screens indicates status, interfacing and diagnos-
tic messages for the SICAM P. The display is automatically refreshed every second.

WARNING
Warning: Danger of explosion of the battery.
Nonobservance of the safety instructions means that death, severe
injuries or considerable material damages can occur.
•Servicing of the battery circuit and replacing of the battery must be performed by qualified
personnel only. Battery may explode if mistreated.
•Do not reverse the polarity!
•Do not disassemble the battery!
•Do not completely discharge the battery!
•Do not throw the battery into a fire!
WARNING
Warning about battery disposal.
Nonobservance of the safety instructions means that death, severe
injuries or considerable material damages can occur.
•When discharged, or when properly secured against short-circuit, lithium batteries can be
disposed of through retailers or at depots run by competent organizations (e.g. in Germany
GRS collection points).
Note
The lithium-batteries in the equipment are subject to special provision 188/A45 of the dangerous
goods regulations of the different transport modes (as in edition 2003, lithium content and tests
of UN Manual of Tests and Criteria).
This is only valid for the original battery or original spare batteries. For general transport security
by shipment as freight: Electric equipment is only to be sent as freight if shut off.
