1. Safety instructions
This description is part of the device. It contains texts and drawings
concerning the correct correct handling of the device and must be
read before installation or use.
Observe the operating instructions. Non-observance of the notes, operation
which is not in accordance with use as prescribed below, wrong installation or
handling can result in serious harm concerning the safety of persons and plant.
These instructions are intended for ”authorised” persons according to EMC and
the low-voltage directives. The device may only be installed, connected and put
into operation by a qualified electrician.
Disconnect the device externally before handling it. If necessary, also disconnect
any independently supplied output load circuits.
If the device is not supplied by the mobile on-bord system (12/24 V battery oper-
ation), it must be ensured that the external voltage is generated and supplied ac-
cording to the criteria for safety extra-low voltage (SELV) as this voltage is sup-
plied without further measures to supply the connected controller, the sensors
and the actuators.
The wiring of all signals in connection with the SELV circuit of the device must al-
so comply with the SELV criteria (safety extra-low voltage, safe electrical separa-
tion 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 instruc-
tions refer to the device the SELV voltage of which is not grounded.
The connection terminals may only be supplied with the signals indicated in the
technical data and/or on the device label and only the approved accessories of
ifm electronic gmbh may be connected.
The device can be operated within a wide temperature range according to the
technical specification indicated below. Due to the additional internal heating the
housing walls can have high perceptible temperatures when touched in hot envi-
ronments.
In case of malfunctions or uncertainties please contact the manufacturer. Tamper-
ing with the device can lead to serious risks for the safety of persons and plant. It
is not permitted and leads to the exclusion of liability and warranty claims.
