INSTALLATION OF THE POWER SUPPLY UNIT
BEFORE INSTALLING THE FEEDING UNIT PERFORM THE CORRECT INSTALLATION
OF THE SENSORS (SEE PAR.5.2) AND THE WIRING OF THE CONNECTION WIRES OF
THE SAME.
1)
Open the package
(par.3.6)
and extract the various components;
2)
Select the input position on the feeding unit of the sensor wires and mark the related
drilling points
devices as shown on pictures 4 and 5.At this stage it is important to
secure cables by cable ties in the appropriate fasteners (see fig. 4-5) placing them as
far as possible from the transformer as shown in the figures.The electric connection
of the control units has to be carried out so as to divide the cables in 230V and 24V. It
is suggested to follow one of the next 3 application ways taking the TF24 unit as an
st
example.According to the 1 method, each cable should pass through cable glands
type PG7 (see fig. 4 for a correct wiring of the control unit). In this case, provide for
holes having 13 mm diameter and 20 mm far one from the other.
nd
The 2 method provides for separate raceways and integral with the box (cables
do not have to be accessible). In this case, provide for holes having 16 mm
diameter for the cables at 230V and having 20 mm diameter for the cables at 24V.
Then use loglines with suitable diameters(see fig. 5 for a correct wiring of the
control unit).
rd
The 3 method consists in drilling holes having 10 mm diameter following the
instructions given in fig. 4 and mounting the cable glands included in the standard
supply.
It is advisable to follow this technique only when cables are not at all
accessible or subject to torsion or traction.
3)
Open the cover of the feeding unit container;
IN THE COVER OF THE VERSION TF24R IT IS INSTALLED THE ELECTRONIC CARD
THAT IS CONNECTED BY THREE WIRES TO THE POWER TRANSFORMER. PAY
UTMOST CARE NOT TO DAMAGE THE ELECTRIC CONNECTIONS OR THE
CONNECTION TO THE TERMINALS.
4)
Using a suitable drill, perform holes having a diameter of 3.5 mm on the two
impressions prearranged for the fastening screws located on the bottom of the
container;
It is suggested to select them diagonally to each other avoiding the ones close to the
transformer;
5)
With a suitable drill, perform in the container holes in according with type of
application decided,how showed at the
point 2
;
6)
Place the container in the pre-selected position and through the holes having 3.5 mm
diameter mark with a pencil the drilling points on the installation support (wall or
other) of the feeding unit. Check the perfect horizontal and vertical alignment;
7)
With a suitable drill, perform holes having a diameter corresponding to the dowels
and to the screws included in the standard supply;
