6.2 Connection of the sensors
Adhere to the SELV criteria (safety extra-low voltage, circuit electrically isolated from other circuits,
ungrounded) when the sensors are connected so that no dangerous contact voltages are applied to
the sensor or transferred to the device.
If the DC circuit is to be grounded (e.g. due to national regulations), the PELV criteria must be adhered
to (protective extra-low voltage, circuit electrically isolated from other circuits).
Sensor and diagnostic electronics supply are not electrically isolated.
