1 Safety instructions
Appropriate use
The PMX amplifier system 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 Manuals. 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
automation technology. This particularly concerns personal and machine
protection.
Additional safety precautions must be taken in plants where malfunctions
could cause major damage, loss of data or even personal injury. In the event
of a fault, these precautions establish safe operating conditions.
This can be done, for example, by mechanical interlocking, error signaling,
limit value switches, etc.
The device must not be connected directly to the mains supply. The
supply voltage must be 10 to 30 V.
General dangers of failing to follow the safety instructions
The PMX system is a state of the art unit and as such is reliable. The module
may give rise to residual dangers if it is inappropriately installed and operated
by untrained personnel.
Any person instructed to carry out installation, starting up, maintenance or
repair of the module must have read and understood the Operating Manual
and in particular the technical safety instructions.
Conditions at the place of installation
−Protect the device from direct contact with water.
−Protect the PMX system from moisture or weather conditions such as rain,
snow, etc. The protection class under the IP standard DIN EN 60 529, is
IP20.
−Do not expose the device to direct sunlight.
−Comply with the maximum permissible ambient temperatures stated in the
specifications.

Safety instructions
A3257−2.0 en/de/fr
−The permissible relative humidity at 31oC is 95 % (non condensing); linear
reduction up to 50% at 40oC.
−The device is classified in overvoltage category II, degree of pollution 2.
−Install the device so that it can be disconnected from the mains at any time
without difficulty.
−It is safe to operate the PMX system up to a height of 2000 m.
Maintenance and cleaning
The PMX system is maintenance-free.
−Before cleaning, disconnect the device from all connections.
−Clean the housing with a soft, slightly damp (not wet!) cloth. You should ne-
ver use solvents, since these could damage the labeling.
−When cleaning, ensure that no liquid gets into the module or the connec-
tions.
Residual dangers
The scope of supply and performance of the PMX system only covers 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
residual dangers. On-site regulations must be complied with at all times.
There must be reference to the residual dangers connected with
measurement technology.
Product liability
In the following cases, the protection provided for the device may be
adversely affected. Liability for device functionality then passes to the
operator:
−The device is not used in accordance with the operating manual.
−The device is used outside the field of application described in this Chapter.
−The operator makes unauthorized changes to the device.
Warning signs and danger symbols
Important instructions for your safety are specifically identified. It is essential
to follow these instructions in order to prevent accidents and damage to
property.

8Safety instructions
A3257−2.0 en/de/fr
The safety instructions take the following form:
SIGNAL WORD
Type of danger
Consequences of non-compliance
Averting the danger
−Warning sign: draws attention to the danger
−Signal word: indicates the severity of the danger (see table below)
−Type of danger: mentions the type or source of the danger
−Consequences: describes the consequences of non-compliance
−Averting: indicates how the danger can be avoided/bypassed
Danger categories under ANSI
Warning sign, signal word Meaning
This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in death or serious
physical injury.
This marking warns of a potentially dangerous
situation in which failure to comply with safety
requirements can result in slight or moderate
physical injury.
This marking draws your attention to a situation in
which failure to comply with safety requirements
can result in damage to property..

Safety instructions
A3257−2.0 en/de/fr
Meaning: Electrostatically sensitive components
Components marked with this symbol can be damaged beyond repair by
electrostatic discharge. Please observe the handling instructions for
components exposed to the risk of electrostatic discharge.
Working safely
A device must not be directly connected to the power supply system.
Supply voltage 10 V ... 30 V (DC).
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 module functionality (HBM recommendation: “Greenline shielding
design”, downloadable from the Internet at http://www.hbm.com/greenline).
Automation equipment and modules must be covered over in such a way that
adequate protection or locking against unintentional actuation is provided
(such as access checks, password protection, etc.).
When the modules 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 interruptions to signal transmission, such as via the
bus interfaces, do not cause undefined states or loss of data in the
automation device.
Conversions and modifications
The device 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
product is delivered from the factory with a fixed hardware and software
configuration. Changes can only be made within the possibilities documented
in the operating manual.
Qualified personnel

10 Safety instructions
A3257−2.0 en/de/fr
Qualified personnel means persons entrusted with siting, mounting, starting
up and operating the product, who possess the appropriate qualifications for
their function.
