3.18 Recommended CAN/RS485 connection
3.18.1 CAN bus connection
The bus has to be terminated by 120 Ω resistors at both ends. External units can be connected on the
CAN bus line in any order, but keeping a line arrangement (no tails, no star) is necessary. Standard
maximum bus length is 200 m for 32C CAN BUS MODE and 900 m for 8C CAN BUS MODE. Shielded
cable must be used. Shielding has to be connected to PE on one side (controller side).
1. For shorter distances (all network components within one room) – picture 1
Interconnect H and L; shielding connect to PE on controller side
2. For longer distances (connection between rooms within one building) – picture 2
Interconnect H, L, COM; shielding connect to PE at one point
3. In case of surge hazard (connection out of building in case of storm etc.) – picture 3
We recommend using the following protections:
 Phoenix Contact (http://www.phoenixcontact.com): PT 5-HF-12DC-ST with PT2x2-BE
(base element)
 Saltek (http://www.saltek.cz): DM-012/2 R DJ
Recommended data cables: BELDEN (http://www.belden.com)
1. For shorter distances: 3105A Paired – EIA Industrial RS-485 PLTC/CM (1x2 conductors)
2. For longer distances: 3106A Paired – EIA Industrial RS-485 PLTC/CM (1x2+1 conductors)
3. In case of surge hazard: 3106A Paired – EIA Industrial RS-485 PLTC/CM (1x2+1 conductors)
3.18.2 RS485 connection
The line has to be terminated by 120 Ω resistors at both ends. External units can be connected on the
RS485 line in any order, but keeping a line arrangement (no tails, no star) is necessary. Standard
maximum link length is 1000 m. Shielded cable must be used. Shielding has to be connected to PE on
one side (controller side).
1. For shorter distances (all network components within one room) – picture 1
interconnect A and B; shielding connect to PE on controller side
2. For longer distances (connection between rooms within one building) – picture 2
interconnect A, B, COM; shielding connect to PE at one point
3. In case of surge hazard (connection out of building in case of storm etc.) – picture 3
We recommend using the following protections:
 Phoenix Contact (http://www.phoenixcontact.com): PT 5-HF-5DC-ST with PT2x2-BE
(base element)(or MT-RS485-TTL)
 Saltek (http://www.saltek.cz): DM-006/2 R DJ
Recommended data cables: BELDEN (http://www.belden.com)
1. For shorter distances: 3105A Paired – EIA Industrial RS-485 PLTC/CM (1x2 conductors)
2. For shorter distances: 3105A Paired – EIA Industrial RS-485 PLTC/CM (1x2 conductors)
