1.6 Safety guidelines
All power sources to the device must always be switched off before carrying out any
installation, repair or maintenance work.
Replace any defective or damaged devices/modules (i.e. in the event of deformed contacts), as the
functionality of the devices cannot be ensured on a long-term basis.
The components are not resistant against materials having seeping and insulating characteristics.
Materials like e.g. aerosols, silicones, triglycerides (found in some hand creams) belong to this group.
If it cannot be ruled out that these materials appear in the component environment, then the
components must be installed in an enclosure that is resistant against the above mentioned
materials.
Clean tools and materials are generally required to operate the device/module.
Only use a soft, wet cloth for cleaning. Soapy water is allowed. Pay attention to ESD.
Do not use solvents like alcohol, acetone etc. for cleaning.
Do not use contact sprays, which could possibly impair the functioning of the contact area
and may cause short circuits.
