What is 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 cables, grouped according to
the maximum distance covered by each single type.

Example types of cables used to connect the CAN network.
For total distances lower than 200 m and networks with a maximum of 4 nodes (example:
up to 3 GAHP + 1 controller) a simple shielded cable 3x0.75 mm may be used.
As shown in Table 6.2 CAN BUS cables type
→
48, the CAN connection requires a CAN
BUS cable with 3 cores. If the cable available has more than 3 coloured wires, use the
wires with the colours indicated in 6.2 CAN BUS cables type
→
48 and cut the remaining
ones.
The ROBUR NETBUS cable is available as an accessory, see Section 8 ACCESSORIES
→
77.
How to connect the CAn BUs cable to the appliance's electronic board
The CAN BUS cable must be connected to the dedicated terminals on the appliance’s
electronic board, as shown below (see Figure 6.9 CAN BUS cable connection
→
49).
