1 SAFETY INSTRUCTIONS
Before starting up, make sure that the mains voltage and type of current stated on the
type plate match the mains voltage and type of current at the place of operation, and that
the circuit being used is adequately protected.
As the device does not have its own power switch, the supply cable connected to it
must not be directly applied to the mains supply. The supply voltage must be 18 to
30 V. According to the VDE directive, these devices must be isolatable from the grid by
means of a switching device (e.g. a power switch). It is essential to ensure that the
device can be quickly disconnected from the mains supply at any time.
The supply connection and the signal and sensor cables must be installed in such a way
that electromagnetic interference does not impair the device functions (recommendation:
HBK "Greenline Shielding Design", download from http://www.hbm.com/Greenline).
Automation equipment and devices must be installed in such a way that adequate
protection and locking against unintentional actuation is provided (e.g. access controls,
password protection, etc.).
When devices are working in a network, the network must be configured in such a way
that malfunctions in individual nodes can be detected and shut down.
Safety precautions must be taken both in terms of hardware and software, so that a line
break or other interruption to signal transmission, such as via the bus interfaces, does not
cause undefined states or loss of data in the automation equipment.
Intended use
The MP55/MP55DP module with connected transducers is to be used exclusively for
measurement tasks and directly related control tasks. Use for any purpose other than the
above is deemed improper use.
In the interests of safety, the device may only be operated as described in the operating
manual. It is also essential to comply with the legal and safety requirements for the
relevant application during use. The same applies to the use of accessories.
Each time before starting up the equipment, you must first run a project planning and risk
analysis that takes into account all the safety aspects of automation technology. This
particularly relates to protection of personal and machinery.
Additional safety precautions to establish safe operating conditions in the event of a fault
must be taken in plants where malfunctions could cause major damage, loss of data or
even personal injury.
This can be done, for example, by error signaling, limit value switches, mechanical
interlocking, etc.

SAFETY INSTRUCTIONS
General risks in case of non-compliance with the safety instructions
The MP55/MP55DP module is a state-of-the-art unit, and as such is failsafe. The device
may pose residual dangers if it is installed or operated by untrained personnel.
Any person involved in setting up, starting up, operating or repairing the device must have
read and understood the operating manual and, in particular, the technical safety
instructions.
Conditions at the place of installation
Protect the devices from moisture, and weather conditions such as rain, snow, etc.
Do not expose the device to direct sunlight. Ensure that there is adequate ventilation.
Maintenance and cleaning
The MP55/MP55DP module is maintenance-free. Please note the following points when
cleaning the housing:
SBefore cleaning, disconnect the device from the power supply.
SClean the housing with a soft, slightly damp (not wet!) cloth. You should never use
solvents, as they could damage the labeling on the front panel and the display.
SWhen cleaning, ensure that no liquid gets into the device or connections.
Residual dangers
The scope of supply and performance of the MP55 covers only a small area of the
measurement technology field. In addition, planners, installers and operators should plan,
implement and manage the safety features of the test and measuring equipment in such
a way as to minimize residual dangers. Applicable regulations must be observed.
The residual dangers associated with test and measuring equipment must be indicated.
Working safely
Error messages may only be acknowledged and reset once the cause of the error is
removed and there is no further danger.
The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE0411 Part 1).
The device must be mounted on a support rail connected to protective conductor
potential. Both the support rail and the MP55/MP55DP module must be free of paint,
varnish and dirt at the place of installation.

SAFETY INSTRUCTIONS
6
To ensure adequate interference immunity, the bus cables (CAN and, for MP55DP,
Profibus DP) must be shielded twisted pairs. The transducer cables must also be
shielded. To ensure adequate interference immunity, use only the Greenline shielding
design (place the shield of the transducer cable on the connector housing).
The cables used for the MP55/MP55DP digital inputs and outputs should not be longer
than 30 meters, and should not exit the building in which the system is located. Otherwise
it will not be possible to ensure that the device works without fault. Strong magnetic
fields or lightning strikes may destroy equipment.
When connecting cables (fitting and extracting terminals), measures must be taken to
prevent electrostatic discharge which could damage the electronics.
The MP55/MP55DP module must be operated with a separated extra-low voltage (18 to
30 V DC supply voltage), which usually supplies one or more consumers within a control
cabinet.
If the device is to be operated on a DC grid1), additional precautions must be taken for the
discharge of surge voltages.
Conversions and modifications
The MP55 module must not be modified in its design or safety features except with our
express consent. Any modification shall exclude any liability on our part for resulting
damage.
In particular, any repair or soldering on motherboards is prohibited. When exchanging
complete modules, use only genuine parts from HBM.
The device is shipped from the factory with a fixed hardware and software configuration.
Changes can only be made within the scope documented in the manuals.
Qualified personnel
This device is only to be installed and used by qualified personnel, strictly in accordance
with the specifications and with the safety rules and regulations which follow.
This includes people who meet at least one of the three following requirements:
SAs project personnel, you are familiar with the safety design features of the
automation equipment, and are accustomed to applying them.
SAs automation plant operating personnel, you have been instructed on how to use the
equipment. You are familiar with the operation of the equipment and technologies
described in this documentation.
SAs a commissioning or service engineer, you have successfully completed training in
the repair of automation plants. You are also authorized to operate, ground and mark
circuits and equipment in accordance with safety engineering standards.
1). Wider-reachingelectric power distribution system (e.g. across multiple control cabinets), possibly
also supplying consumers with high rated currents.

SAFETY INSTRUCTIONS
During use, compliance with the legal and safety requirements for the relevant
application is also essential. The same applies to the use of accessories.
Qualified personnel means persons entrusted with installing, mounting, starting up and
operating the product, who possess the appropriate qualifications for their work.

3.2 General
The MP55/MP55DP module from the PME product line is a carrier-frequency amplifier
suitable for connecting force transducers, pressure transducers, torque transducers,
displacement transducers and load cells in a wide variety of technologies. The MP55
module is set up and parameterized via a keyboard and display, or by using the PME
Assistant. The PME Assistant provides a simple user interface under MS-Windows for
parameterizing the modules (in the "PME Assistant" program help).
