If the appliance is an
6.
intermediate node repeat the operations from step 2 to step
5 for the other cables required (in this way you will have two cable lengths each
one without the jacket on one end). Twist together the cores with the same color
and connect them to the orange connector, as shown in detail "B" of Figure 6.10

50.
Fix the CAN BUS cable (or two cables, according to the type of node being con-
7.
nected) to the holding bracket in the upper part of the electrical panel so that the
pulled-back shielding is in solid touch with the metal bracket. The cables must be
firmly held in place by the bracket if pulled.
In order to position the jumpers on the electronic board according to the type of node
being configured:
If the appliance is a
•
terminal node on the network (i.e. 3 wires are inserted in the
orange connector on the board): set the jumpers as shown in detail "A" of Figure
6.10 Electrical wiring diagram
→

If the appliance is an
•
intermediate node on the network (i.e. 6 wires are inserted
in the orange connector on the board); set the jumpers as shown in detail "B" of
Figure 6.10 Electrical wiring diagram

After finished with all the above operations, close the electrical panel and refit the
8.
front panel of the appliance.
How to connect the CAn BUs cable to the ddC
The CAN bus cable is connected to the specific orange connector (P8) supplied with the
DDC in a bag.
Before working on the DDC, make sure that it is off.
The DDC, like the controller on the appliance, has jumpers that must be moved so that it
can be configured as an intermediate or terminal node. The position of the jumpers on a
new DDC is CLOSED.
To connect the CAN bus cable to a DDC:
You will need: DDC not powered up.
Depending on the type of node being configured, set the DDC's jumpers J21 as

shown in detail "A" or detail "B" in Figure 6.17 detail wires and jumpers J21 - termi-
nal/intermediate node CCI/DDC
→
59. If necessary, open the DDC's back pa nel (4
screws); after jumpers J21 have been correctly positioned, close the cover again
and retighten the 4 screws.
If the DDC is an
•
intermediate node on the network (with no. 6 wires in the or-
ange connector "P8"): set the jumpers "J21" as shown in detail "B" of Figure 6.17
detail wires and jumpers J21 - terminal/intermediate node CCI/DDC

59: Jump-
ers OPEN.
If the DDC is an
•
terminal node on the network (with no. 3 wires in the orange con-
nector "P8"): set the jumpers "J21" as shown in detail "A" of Figure 6.17 detail wires
and jumpers J21 - terminal/intermediate node CCI/DDC
→
59: Jumpers CLOSED.
Prepare the orange CAN bus connector, from the supplied sleeve.
2.
Cut a length of cable long enough to allow installing it without kinking.
3.
Remove the sheath for a length of approximately 70-80 mm, taking care not to cut
4.
the shielding (metallic shield and/or aluminium sheet and, if present, the bare con-
nector in contact with the shield) and wires contained inside.
