Only use this display
– in a way according to its intended
purpose
– if its technical condition is perfect
– adhering to the operating
instructions and the general
safety instructions.
The digital display may be used only as a
panel-mounted device. Applications of this
product may be found in industrial
processes and controls, in manufacturing
lines for the metal, wood, plastics, paper,
glass, textile and other processing industries.
Over-voltages at the terminals of the digital
display must be kept within the limits in
Category II
If the digital display is used to monitor
machines or processes in which, in case of
a failure of the device or an error made by
the operator, there might be risks of
damaging the machine or causing accidents to the operators, it is your
responsibility to take appropriate safety
measures.
