Electrical Installation

The device must be disconnected from
any power supply prior to any
installation or maintenance work. Make
sure that no more voltages
DANGER
CAUSE AN ELECTROCUTION
AC-powered devices must only be
connected to the low-voltage network
via a switch or circuit breaker installed
close to the device and marked as their
disconnecting device.
Installation or maintenance work must
only be carried out by qualified
personnel 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
externally for its proper operation.
Information about the prescribed fuses
can be found in the technical
DANGER
information.
The relay outputs are not protected
internally in the device. Without suitable
protection of the relay outputs,
undesired heat development or even
fire may occur. The relay outputs must
be protected externally by the
manufacturer of the plant. It must also
be made sure that, even in case of a
malfunction, the values stated in the
technical data are under no
circumstances exceeded.
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 voltage of
250V.
The cables and their insulation must be designed
for the planned temperature and voltage ranges.
Regarding the type of the cables, adhere to the
applicable standards of the country and of the
plant. The cross sections allowed for the screw
terminals can be found in the technical 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 connecting lines!
Interference (e.g. from switch-mode power supplies,
motors, clocked controllers or contactors) can be
reduced by means of appropriate cable routing and
wiring.
Measures to be taken:
Use only shielded cable and control lines.
Connect 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.
2.4
The front side of the unit should only be cleaned using
a soft damp (water!) cloth. Cleaning of the embedded
rear side is not planned and is the responsibility of the
service personnel or of the installer.
In normal operation, this device is maintenance-free.
Should the device nevertheless not operate properly,
it must be sent back to the manufacturer or to the
supplier. Opening and repairing the device by the user
is not allowed and can adversely affect the original
protection level.
