Safety requirements
A module must not be directly connected to a power supply system. The
maximum allowed supply voltage is DC 10 to 30 V.
The supply voltage connection as well as the signal and sense leads must be
installed in such a way that electromagnetic interference does not adversely
affect device functionality. (HBM recommendation: "Greenline shielding
design", can be downloaded from http://www.hbm.com/Greenline).
Automation equipment and devices must be covered over 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 interference in individual nodes can be detected and the nodes
can be 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
device.
Conditions on site
For modules with equipment protection level IP20:
S Protect the modules from moisture and dampness or weather such as rain,
snow, etc.
S The allowed relative humidity at 31 °C is 80 % (non condensing); linear
reduction up to 50 % at 40 °C.
S Make sure that the side ventilation openings are not covered.
For all modules:
S Do not expose the measuring instrument to direct sunlight.
S Please observe the maximum allowed ambient temperatures stated in the
specifications.
