which is not in accordance with use as prescribed below, wrong installation or
incorrect handling can seriously affect the safety of operators and machinery�
2.2 Target group
These instructions are intended for authorised persons according to the EMC and
low-voltage directives� The unit must be installed, connected and put into operation
by a qualified electrician trained in safety technology�
2.3 Electrical connection
The device is designed for supply via a mobile on-board system (12/24 V DC
battery operation)�
Disconnect the unit externally before handling it� If necessary, also disconnect any
independently supplied output load circuits�
If the device 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 supplied
according to the criteria for safety extra-low voltage (SELV) as this voltage is
supplied 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 device must also
comply with the SELV criteria (safety extra-low voltage, safe electrical isolation
from other electric circuits)�
If the supplied SELV voltage is externally grounded (SELV becomes PELV), the
responsibility lies with the user and the respective national installation regulations
must be complied with� All statements in this document 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 from
ifm electronic gmbh may be connected�
2.4 Housing temperature
As described in the technical specifications below the device can be operated
in a wide ambient temperature range� Because of the additional internal heating
the housing walls can have high perceptible temperatures when touched in hot
environments�
