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:
SThe device is not used in accordance with the operating manual.
SThe device is used outside the field of application described in this chapter.
SThe operator makes unauthorized changes to the device.
Working safely
A device must not be directly connected to the power supply system. Sup
ply 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 func
tionality (HBM recommendation: "Greenline shielding design", downloadable
from the Internet at http://www.hbm.com/greenline).
Automation equipment and modules must be designed in such a way that ade
quate protection or locking against unintentional actuation is provided (e.g. ac
cess 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, e.g. via the bus
interfaces, do not cause undefined states or loss of data in the automation de
vice.
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 com
ponents) is prohibited. When exchanging complete modules, use only original
parts from HBM.
