Working safely
A device must not be directly connected to the power
supply system. Supply voltage DC 10 V … 30 V.
The supply connection and all other connections must be
installed in such a way that electromagnetic interference
does not adversely affect device functionality (HBM rec
ommendation: "Greenline shielding design", download
able from the Internet at http://www.hbm.com/greenline).
Automation equipment and modules must be designed in
such a way that adequate protection or locking against
unintentional actuation is provided (e.g. access checks,
password protection, etc.).
When the modules are working in a network, these net
works 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 hard
ware and software, so that a line break or other interrup
tions to signal transmission, e.g. via the bus
interfaces, do not cause undefined states or loss of data
in the automation device.
Conversions and modifications
The 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 resultant damage.
In particular, any repair or soldering work on
motherboards (exchanging components) is prohibited.
