Phase B: connect the CAN BUS cable to the appliance
The CAN BUS cable must be connected to the orange socket on the machine’s on-bo-
ard controller (see detail "D" in Figure 5.15 Connection of CAN BUS cable to connector
P8 on controller AY10
→
59).

To connect the CAN BUS cable to the DDC, proceed as follows (references in Figure
5.15 Connection of CAN BUS cable to connector P8 on controller AY10
→
59):
You will need: appliance not powered up. Necessary equipment and materials.
Remove the front panel of the appliance and the cover of the electrical panel.
1.
Cut a length of cable, long enough to allow it to be installed without kinking.
2.
Having chosen one end of the length of cable, remove the sheath from a length
3.
of approximately 70-80 mm, taking care not to cut the wires contained inside,
the shielding (metallic shield and/or aluminium sheet) and, if present, the bare
connector in contact with the shield and the wires contained within.
If the cable is too thin to be held in place in the cable holder bracket (detail C),
4.
make it thicker by wrapping insulating tape around it on the sheath in the area
adjacent to the stripped part (to an approximate diameter of 12-13 mm).
Pull back the shielding in the sheathe; apply electrician’s tape to the end of the
5.
shielding as pulled back (detail A).
Pull the orange connector (detail D) out of socket "P8" on the controller.
