WIRING

To interconnect the Velbus modules the use of twisted-pair cable (EIB 2x2x0.8mm2, UTP 8x0.51mm - CAT5 or

equivalent) is recommended.

When a lot of modules (more than 10) are connected to the cable or longer cable lengths (more than 50m) are used, it

is important to use a cable with appropriate diameter (0.5mm² or higher).

Connect the bus to the module (beware of the polarity).

Connect the 12V to 18V direct current to the module (beware of the polarity).
