2.2 Mounting in a control panel
Mount the device away from heat
sources and avoid direct contact with
corrosive liquids, hot steam or similar.
Provide a free space of 10mm all
around the device for its ventilation.
The device should be mounted so that
the terminals are out of the reach of the
operator and cannot be touched by
him. When mounting the device, consi-
der the fact that only the front side is
classified as accessible for the operator.
Mounting instructions
1. Remove the mounting clip from the device.
2. Insert the device from the front into the panel
cut-out, ensuring the front-panel gasket is cor-
rectly seated.
3. Slide the fixing clip from the rear onto the
housing, until the spring clamps are under ten-
sion and the upper and lower latching lugs
have snapped into place.
Note: In case of proper installation, IP65 can be
reached on the front side.
2.3 Electrical Installation
The device must be disconnected
from any power supply prior to any
installation or maintenance work.
Make sure that no more voltages
LIABLE TO CAUSE AN ELECTRO-
CUTION are present.
AC-powered devices must only be
connected to the low-voltage network
via a switch or circuit breaker instal-
led close to the device and marked
as their disconnecting device.
Installation or maintenance work must
only be carried out by qualified per-
sonnel and in compliance with the
applicable national and international
standards.
Take care to separate all extra-low
voltages entering or exiting the device
from hazardous electrical conductors
by means of a double or reinforced
insulation (SELV circuits).
The device must be protected exter-
nally for its proper operation. Informa-
tion about the prescribed fuses can
be found in the technical information.
• During installation, make sure that the supply
voltage and the wiring of the output contacts
are both fed from the same mains phase, in
order not to exceed the maximum permitted vol-
tage of 250V.
• The cables and their insulation must be desig-
ned for the planned temperature and voltage
ranges. Regarding the type of the cables, adhe-
re to the applicable standards of the country
and of the plant. The cross sections allowed for
the screw terminals can be found in the techni-
cal data.
• Before starting the device, check the cables for
proper wiring and tightening. The screws of
unused screw terminals must be screwed to the
stop, so that they cannot loosen and get lost.
• The device has been designed for overvoltage
category II. If higher transient voltages cannot
be excluded, additional protection measures
must be taken in order to limit the overvoltage
to the values of CAT II.
Advice on noise immunity
All connections are protected against external
sources of interference. The installation location
should be chosen so that inductive or capacitive
interference does not affect the device or its con-
necting lines! Interference (e.g. from switch-mode
power supplies, motors, clocked controllers or
contactors) can be reduced by means of appro-
priate cable routing and wiring.
Measures to be taken:
Use only shielded cable and control lines. Con-
nect shield at both ends. The conductor cross-
section of the cables should be a minimum of
0.14 mm².
The shield connection to the equipotential bonding
should be as short as possible and with a contact
area as large as possible (low-impedance).
Only connect the shields to the control panel, if
the latter is also earthed.
Install the device as far away as possible from
noise-containing cables.
Avoid routing signal or control cables parallel to
power lines.
