The instructions are for authorised persons according to the EMC and low
voltage guidelines. The controllers must be installed and commissioned by a
skilled electrician (programmer or service technician).
If the unit is not supplied by the mobile on-board system (12/24 V battery
operation) it must be ensured that the external voltage is generated and sup-
plied according to the criteria for safety extra-low voltage (SELV) as this is sup-
plied 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 sepa-
ration from other electric circuits).
If the supplied SELV voltage has an external connection to ground (SELV
becomes PELV) the responsibility lies with the user and the respective national
regulations for installation must be complied with. All statements in these
operating 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.

technical specification indicated below. Due to the additional self-heating the
housing walls can have high perceptible temperatures when touched in hot
environments.
