Working safely
Notice
The device must not be directly connected to the DC
voltage 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 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.
