> CHARACTERISTICS OF THE CAN BUS CABLE

The cable to be used must be suitable for CAN BUS applications.

The following table gives details of some types of CAN bus cable, grouped according to the maximum distance covered by each

single type.

Example types of cables used to connect the CAN network.

For overall distances to cover of ≤200 m and networks with a maximum of 6 nodes (a typical example: 1 DDC + 5 devices), a

simple 3 x 0�75 mm

shielded cable may be used.

As shown in Table 6.2

→

43, the CAN connection requires a CAN bus cable with 3 wires. If the available cable has more than 3 coloured

wires, use the wires with the colours indicated in 6.2

→

43 and cut the remaining ones.

The ROBUR NETBUS cable is available as an accessory (see Section 8

→

58).

> CONNECTION PROCEDURE

Instructions for the specific operations to be carried out for the connection of the CAN bus cable follow:

▶

Step A: connect the CAN-BUS cable to the CCI/DDC.

▶

Step B: connect the CAN-BUS cable to the appliance.

The two steps must done in both cases illustrated in Figure 6.17

→

48 (wiring diagram for 1 DDC connected to a single appli-

ance) and Figure 6.18

→

49 (wiring diagram for 1 DDC connected to multiple appliances).

Step A: connect the CAN-BUS cable to the CCI/DDC
The CAN bus cable connects to the specific orange connector supplied with the DDC, as shown in Figure 6.12
