Figure 20 – EXAMPLE CONNECTION OF DDC TO SINGLE ACF60-00 UNIT (2 nodes network) AND TO N.2
ACF60-00 UNITS CONNECTED ON THE SAME HYDRONIC SYSTEM (3 nodes network).

SYSTEM (4 nodes network).
CAN-BUS wire connection
If the network connection is max 650 ft cable long and has max 6 nodes (e.g.: 5 ACF60-00 + 1 DDC) a
simple shielded wire 3 x 18 AWG is required.
For major lengths, the CAN-BUS wire should be compatible with Standards Honeywell SDS.
The next Table shows some examples of these wires, according to the total length of the wire itself:

TURCK type 531 BLACK = H WHITE = L BROWN = GND 656
Table 17 – EXAMPLE OF TYPES OF WIRES USED FOR CAN-BUS
NOTE: “GND” is the common signal wire, and NOT a ground connection.
Take the CAN-BUS wire of suitable length for the connection between DDC and the unit and, for every
network or CAN-BUS wire segments (from a node to another) cut sheath of the wire from both terminal for
about 3” length and connect them to the proper nodes, on the electronic control board (S61) or on DDC.
