1.4 Safety Information
When connecting the device to your installation and during operation, the fol-
lowing safety notes must be observed:
Danger
The WAGO-I/O-SYSTEM 750 and its components are an open system. It
must only be assembled in housings, cabinets or in electrical operation
rooms. Access is only permitted via a key or tool to authorized qualified per-
sonnel.
Danger
All power sources to the device must always be switched off before carrying
out any installation, repair or maintenance work.
Warning
Replace defective or damaged device/module (e.g. in the event of deformed
contacts), as the functionality of fieldbus station in question can no longer be
ensured on a long-term basis.
Warning
The components are not resistant against materials having seeping and insu-
lating properties. Belonging to this group of materials is: e.g. aerosols, sili-
cones, triglycerides (found in some hand creams). If it cannot be ruled out
that these materials appear in the component environment, then the compo-
nents must be installed in an enclosure that is resistant against the above men-
tioned materials. Clean tools and materials are generally required to operate
the device/module.
Warning
Soiled contacts must be cleaned using oil-free compressed air or with ethyl
alcohol and leather cloths.
Warning
Do not use contact sprays, which could possibly impair the functioning of the
contact area.
Warning
Avoid reverse polarity of data and power lines, as this may damage the de-
vices.
ESD (Electrostatic Discharge)
The devices are equipped with electronic components that may be destroyed
by electrostatic discharge when touched.
