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.

Do not use any contact spray!
Do not use any contact spray. The spray may impair contact area functionality in
connection with contamination.

Do not reverse the polarity of connection lines!
Avoid reverse polarity of data and power supply lines, as this may damage the
devices involved.

Avoid electrostatic discharge!
The devices are equipped with electronic components that may be destroyed by
electrostatic discharge when touched. Please observe the safety precautions
against electrostatic discharge per DIN EN 61340-5-1/-3. When handling the
devices, please ensure that environmental factors (personnel, work space and
packaging) are properly grounded.

Perform insulation tests with direct current (DC)!
Both the supply voltage and control voltage side are capacitively coupled to the
DIN rail. If the modules are mounted on the DIN rail, application of an AC
voltage between the two potentials can lead to the destruction of the device.
Use only direct current (DC) for insulation testing.
To avoid destroying the device, discharge the device completely before applying
the test voltage again.
