CONNECTION
To connect the Velbus modules with each other, a twisted pair cable is recommended (EIB 2x2x0.8mm², UTP
4x2x0.51mm² - CAT5 or equivalent).
When a lot of modules (more than 10) are connected on the Velbus cable or the Velbus cable is very long (over 50m)
it is important to foresee a cable with sufficient wire diameter (0.5mm
2
of more).
Connect the bus and power supply to the module (mind the polarity).
Connect the pushbuttons. Unused wires should be isolated.
Remark:
DO NOT extend the connection
