Safety Advice (Precautions)
For installing and operating purposes of the relevant device to your system the
following safety precautions shall be observed:
Do not work on components while energized!
All power sources to the device shall be switched off prior to performing any
installation, repair or maintenance work.
Installation only in appropriate housings, cabinets or in electrical operation
rooms!
The WAGO-I/O-SYSTEM 750 and its components are an open system. As such,
install the system and its components exclusively in appropriate housings,
cabinets or in electrical operation rooms. Allow access to such equipment and
fixtures to authorized, qualified staff only by means of specific keys or tools.
Replace defective or damaged devices!
Replace defective or damaged device/module (e.g., in the event of deformed
contacts), since the long-term functionality of device/module involved can no
longer be ensured.
Protect the components against materials having seeping and insulating
properties!
The components are not resistant to materials having seeping and insulating
properties such as: aerosols, silicones and triglycerides (found in some hand
creams). If you cannot exclude that such materials will appear in the component
environment, then install the components in an enclosure being resistant to the
above-mentioned materials. Clean tools and materials are imperative for handling
devices/modules.
Cleaning only with permitted materials!
Clean soiled contacts using oil-free compressed air or with ethyl alcohol and
leather cloths.
