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
wires for the pushbuttons

VMB8PBU – ed.1 | 8-channel pushbutton module 7
Connecting a LED on a BTicinoTM pushbutton
Glue the blue (type VMBLDB) or amber (type VMBLDAB) LED on the pushbutton.
The black connection wire ‘PB’ of the LED is combined with one of the eight pushbutton connection wires.
The white connection wire ‘C’ of the LED is combined with the common connection wire ‘COM’ for the pushbuttons.

TERMINATOR
In normal circumstances only 2 ‘TERM’ terminators must be foreseen in a complete Velbus installation. Usually this
will be on one module inside the distribution box and on the module the furthest from the distribution box.
In all other cases it must be removed.
Remark:
In a wiring scheme with a lot of branches a
terminator is placed on a module inside the
distribution box and on the control panel
furthest from the distribution box. Should
communication problems occur, an additional
terminator can be placed on another branch.
However, the number of terminators should
be kept to a minimum as additional
terminators place a heavy load on the bus.
