1.3 Use according to the intended purpose
The application area for this device lies in industrial proces-
ses and controls, in the fields of manufacturing lines for the
metal, wood, plastics, paper, glass, textile and other like in-
dustries with a degree of contamination of 2. Over voltages
at the terminals of the device must be kept within the limits
of Over voltage Category II. The device is not suitable for
use in hazardous areas and for areas excluded from EN
61010 Part 1. The device may only be operated indoors as
a panel-mounted device. However, in certain conditions, an
outdoor operation is also allowed. It may be operated up to
an altitude of 2,000 m. Use for any purpose over and bey-
ond this will be deemed as not in accordance with its inten-
ded purpose.
If the device is used to monitor machines or processes in
which, in the event of a failure of the device or an error
made by the operator, there might be the risk of damaging
the machine or causing an accident to the operators, then it
is your responsibility to take the appropriate safety measu-
res.
1.4 Mounting in a control panel
Mount the device away from heat sources and avoid direct
contact with corrosive liquids, hot steam or similar. When
mounting the device, make sure it is sufficiently cooled.
1.5 Mounting instructions
– Remove the mounting clip from the device.
– Insert the device from the front into the panel cut-out, en-
suring the front-panel gasket is correctly seated.
– Slide the fixing clip from the rear onto the housing, until
the spring clamps are under tension and the upper and
lower latching lugs have snapped into place.
1.6 Electrical Installation
This device is powered by the mains voltage! It
must be disconnected from the power supply, be-
fore any installation or maintenance work is car-
ried out. AC-powered devices must only be
connected to the low-voltage network via a switch or circuit
breaker.
Installation or maintenance work must only be carried out
by qualified personnel.
– Correct operation of the device requires the mandatory
use of the appropriate external safety fuse. Advice con-
cerning the recommended fuse protection can be found in
the relevant instruction manual.
In order to respect the fire protection regulations, 8 A/150
VA shall not be exceeded on the counter in case of a de-
fect!
– Do not wire the terminals of the device that are not used.
– The pin assignment of the connectors, as well as the ma-
ximum admissible values, must obligatorily be observed.
– During installation, make sure that the supply voltage and
the wiring of the output contacts (if any) are powered by
the same mains phase, in order not to exceed the max.
voltage of 250 V! The indications of the Instructions ma-
nual must obligatorily be adhered to!
– If the device is equipped with a PE connection, the latter
must obligatorily be connected with a low impedance.
– An EMC-compliant installation is a prerequisite to reach
EC conformity.
