*: With an input delay of 0.5 ms, shielded cables must be used for the digital inputs and the sensor
supply.
With 3 ms input delay, shielded cables must be used if there is a danger of overvoltage on the signal
lines (see section "Electromagnetic Compatibility") to prevent possible passivation of the fail-safe
digital inputs and the sensor power supply switching off. If unshielded signal lines are used, the safe
behavior of the process variables is ensured.
**: Operating below the permissible supply voltage is only permissible for the repair time. See chapter
"Introduction (Page 61)."
***: For more information on the requirements for sensors and actuators, see "Wiring and Fitting
Modules".
