Safety instructions
Working safely
Notice
The device must not be directly connected to the DC voltage supply system.
Supply voltage 10 V ... 15 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 devices must be installed in such a way that
adequate 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 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.
