Safety instructions
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.
