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.
Use only direct current (DC) for insulation testing!
Both the system voltage and field voltage side are capacitively coupled to the
DIN-rail. If an I/O module is mounted on the DIN-rail, application of an AC voltage
between the DIN-rail and at least one of these two potentials can lead to the
destruction of the module.
Use only direct current (DC) for insulation testing. To avoid destroying the I/O
module, you must discharge it completely before applying the test voltage again.
Use regulated power supply!
A fluctuation in the input voltage would also affect the output. The use of a
regulated power supply unit is therefore recommended for the field supply.
