Technical data

As shown in Table 6.2 CAN BUS cables type → 51, 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 → 51 and cut the remaining 
ones.
The ROBUR NETBUS cable is available as an accessory, see Section 8 ACCESSORIES → 81.
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 6.8 CAN BUS cable connection → 52).

Before working on the electrical panel of the appliance, make sure that power supply is 
off.
 Cut a length of cable long enough to allow installing it without kinking.1. 
 On one end of the cable, remove the jacket for a length of approximately 70-80 2. 
mm, taking care not to cut the shielding (metal mesh and/or aluminium sheet and, 
if present, the bare connector in touch with the shield) and the wires contained 
within.
 If the cable is too thin to be held in place in the cable holding bracket (detail C in 3. 
Figure 6.8 CAN BUS cable connection → 52), make it thicker by wrapping insulat-
ing tape around the jacket close to the stripped part (to an approximate diameter 
of 12-13 mm).
 Pull back the shielding on the jacket; apply isolating tape to the end of the shield-4. 
ing as pulled back (detail A, Figure 6.8 CAN BUS cable connection → 52).
 If the appliance is a 5.  terminal node of the network connect the three  coloured 
wires to the orange connector as shown in detail "A" of Figure 6.9 Electrical wir-
ing diagram → 53. Respect the correct indications L, H, GND provided in Table 6.2 
CAN BUS cables type → 51, on the figure and on the electronic board below the 
connector.
 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 6.9 
Electrical wiring diagram → 53.
