‣
Switch off the supply voltage before connecting the device.
‣
Connect the potential matching line to the external ground terminal of the transmitter
before connecting the device.
‣
Connect the protective ground to the protective ground terminal.
‣
The cables must be adequately insulated, with due consideration given to the supply
voltage and the overvoltage category.
‣
The connecting cables must offer adequate temperature stability, with due
consideration given to the ambient temperature.
