4.2 Installation location for agriculture
When using for animal keeping, do not install the device directly in the stable but in a
separate room with a lower pollutant load. This helps to avoid damages caused by
pollutant gases (e.g. ammonia fumes, hydrogen sulphide fumes).
5 Electrical installation
5.1 EMC-compatible installation of control lines
Pay attention to maintain suf
fi
cient distance from powerlines and motor wires to prevent
interferences.
When using a shielded cable the shield must be connected (as short and with as low an
induction as possible!) to the PE conductor on one side at the signal input (of the
evaluation unit).
5.2 Connection Voltage supply
Connection Voltage supply at terminals:
“
+U
S
”
and
“
GND
”
. Here, it must be strictly
observedt hat the mains voltage lies within the llowable olerance peci
fi
cations (see
Technical data and nameplate af
fi
xed to the side).
Danger due to electric current
Only PELV current sources which ensure safe electrical isolation of the operating voltage
in accordance with IEC/DIN EN 60204-1 must be used.
There is no potential isolation between supply voltage and output signal.
5.3 Sensor connection
Connection of temperature sensor for measuring actual value (not in scope of delivery)
to terminals
“
TF
”
. It is possible to connect ZIEHL-ABEGG sensors of series
“
TF..
”
(KTY81-210) or PT1000 temperature sensors (it must be paid attention to no polarity).
For a high interference immunity a capacitor must be connected directly to the sensor (1
nF parallel). With ZIEHL-ABEGG temperature sensors type TF.. (KTY81-210) a capacitor
is integrated.
Attention!
Never apply line voltage to analog inputs!
