without further measures to the connected controller, the sensors, and the
actuators.
The wiring of all signals in connection with the SELV circuit of the unit must also
comply with the SELV criteria (safe extra-low voltage, safe electrical separation
from other electric circuits).
If the supplied SELV voltage has an external connection to ground (SELV beco-
mes PELV) the responsibility lies with the user and the respective national regu-
lations for installation must be complied with. All statements in these opera-
ting instructions refer to the unit the SELV voltage of which is not grounded.
The terminals may only be supplied with the signals indicated in the technical
data or on the unit label and only the approved accessories of ifm electronic
gmbh may be connected.
The unit can be operated within a wide temperature range according to the
technical specification indicated below. Due to the additional self-heating the
