How to connect the CAN bus cable to the appliance
To connect the CAN bus cable to the S61 electronic board
(Paragraph 1.5 p. 12), located in the electrical panel inside the
unit, (Figure 4.2 p. 27 and 4.3 p. 27):
1. Access the electrical board of the appliance according to the
Procedure 4.2
p. 25.
2.
Connect the CAN bus cable to the GND (shielding/ground-
ing) + L and H terminals (two signal wires).
3. Place the CLOSED J1 Jumpers (Detail A) if the node is ter-
minal (one connected CAN bus cable section only), or OPEN
(Detail B) if the node is intermediate (two connected CAN
bus cable sections).
4. Connect the DDC to the CAN bus cable according to the in-
structions of the following Paragraphs and DDC Manual.
