Safety instructions
Before commissioning, make sure that the mains voltage and type of current
stated on the identification plate match the mains voltage and type of current
at the place of operation and that the circuit used is efficiently 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 the the VDE directive,
there must be a switching device present (such as a power switch) to
disconnect these devices from the mains. It is essential to ensure that
the device can be quickly disconnected from the mains supply at any
time.
The supply connection, as well as the signal and sense leads, must be
installed in such a way that electromagnetic interference does not adversely
affect device functionality (HBM recommendation: “Greenline shielding
design", downloadable from the Internet at http://www.hbm.com/Greenline).
Automation equipment and devices must be installed in such a way that ade
quate protection or locking against unintentional actuation is provided (e.g.
access checks, password protection, etc.).
When devices are working in a network, these networks must be designed 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, do not cause undefined states or loss of data in the automa
tion device.
Intended use
The MP55 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 to be non‐designated use.
In the interests of safety, the device should only be operated as described in
the Operating Manual. It is also essential to comply with the legal and safety
requirements for the application concerned 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

5

A0563-7.2 en HBM
automation technology. This particularly concerns personal and machine
protection.
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.
General dangers of failing to follow the safety instructions
The MP55 module is a state of the art unit and as such is failsafe. The device
may give rise to residual dangers if it is inappropriately installed and operated
by untrained personnel.
Any person instructed to carry out installation, commissioning, maintenance or
repair of 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 dampness or weather such as rain,
snow, etc.
Do not expose the device to direct sunlight. Ensure that there is adequate
ventilation.
Maintenance and cleaning
The MP55 module is maintenance free. Please note the following points when
cleaning the housing:
- Before cleaning, disconnect the device from the power supply.
- Clean the housing with a soft, slightly damp (not wet!) cloth. You should
never use solvent, since this could damage the labeling on the front panel
and the display.
- When 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 measurement technology. In addition, equipment planners, installers and
operators should plan, implement and respond to the safety engineering
considerations of measurement technology in such a way as to minimize resi
dual dangers. On‐site regulations must be complied with at all times. There
must be reference to the residual dangers connected with measurement tech
nology.
Any risk of residual dangers when working with the MP55 is pointed out in
these instructions by means of the following symbols:
Symbol: WARNING
Meaning: Dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements can lead to death or serious physical injury.
Symbol: CAUTION
Meaning: Possibly dangerous situation
Warns of a potentially dangerous situation in which failure to comply with
safety requirements could lead to damage to property and slight or moderate
physical injury.
Symbol: NOTE
Means that important information about the product or its handling is being
provided.
Symbol:
Meaning: Statutory waste disposal mark
In accordance with national and local environmental protection and material
recovery and recycling regulations, old devices that can no longer be used
must be disposed of separately and not with normal household garbage. If
you need more information about waste disposal, please contact your local
authorities or the dealer from whom you purchased the product.

Symbol:
Meaning: CE mark
The CE mark enables the manufacturer to guarantee that the product com
plies with the requirements of the relevant EC directives (the Declaration of
Conformity can be found at http://www.hbm.com/HBMdoc).
Working safely
Error messages should only be acknowledged once the cause of the error is
removed and no further danger exists..
The device complies with the safety requirements of DIN EN 61010 Part 1
(VDE 0411 Part 1).
The device must be mounted on a support rail connected to grounded con
ductor potential. Both the support rail and the MP55/MP55DP module must be
free of paint, varnish and dirt at the point of installation.
To ensure adequate immunity from interference, the bus cables (CAN and for
MP55DP, Profibus DP) must be shielded, twisted‐pair lines. The transducer
cables must also be shielded. To ensure adequate immunity from interfe
rence, use only the Greenline shielding concept (place the shield of the trans
ducer cable onto the connector housing).
The cables of the MP55/MP55DP digital inputs and outputs that are used
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 perfectly. Strong magnetic fields or lightning strikes may have a
destructive effect.
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 vol
tage (18 to 30 V DC supply voltage), which usually supplies one or more con
sumers within a control cabinet.
Should the device be operated on a DC voltage network1), additional precau
tions must be taken to discharge excess voltages.
1) Distribution system for electrical energy with greater physical expansion (over several control cabinets, for
example) that may also supply consumers with high nominal (rated) currents.

Conversions and modifications
The MP55 module must not be modified from the design or safety engineering
point of view except with our express agreement. Any modification shall
exclude all liability on our part for any damage resulting therefrom.
In particular, any repair or soldering work on motherboards is prohibited.
When exchanging complete modules, use only original parts from HBM.
The device is delivered from the factory with a fixed hardware and software
configuration. Changes can only be made within the possibilities documented
in the manuals.

1.2 General
The MP55 module from the PME product line is a carrier‐frequency amplifier
suitable for connecting force transducers, pressure transducers, torque trans
ducers, displacement transducers and load cells for a wide variety of techno
logies. The MP55 module is set up and parameterized via a keyboard and dis
play, 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" Online Help).
