Safety instructions
This description is part of the unit. It contains texts and drawings
concerning the correct handling of the module and must be read be-
fore installation or use.
Observe the information of the description. Non-observance of the notes, opera-
tion 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.
The instructions are for authorised persons according to the EMC and low volt-
age guidelines. The process and dialogue modules must be installed and commis-
sioned by a skilled electrician (programmer or service technician).
If the unit is not supplied by the mobile on-board system (12/24 V battery opera-
tion) 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 is supplied with-
out 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 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 unit the SELV voltage of which is not grounded.
The connectors 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 tech-
nical specification indicated below. Due to the additional self-heating the housing
walls can have high perceptible temperatures when touched in hot environments.
In case of malfunctions or uncertainties please contact the manufacturer. Tamper-
ing with the unit can lead to considerable risks for the safety of persons and
plant. It is not permitted and leads to the exclusion of any liability and warranty
claims.
