For this, Daikin recommends shielded lines with the following
characteristics:
– Standardisation according to ISO 11898, UL/CSA type CMX
(UL 444)
– PVC outer sheath with flame retardancy according to IEC
60332-1-2
– Up to 40 m, minimum cross-section 0.75 mm
ductor cross-section necessary with increasing length.
Commercially available junction boxes can be used to connect
CAN bus lines of several RoCon devices.
Ensure that mains, sensor and data bus lines are routed sepa-
rately. Use only cable ducts with separators or separate cable
ducts spaced at least 2 cm apart. Line crossings are permissible.
A maximum of 16 devices with a total line length of up to 800 m
can be connected in the entire RoCon system.
