This installation manual guides you through the process of installing the Velbus VMBEL-series and
VMBGP-series glass control panels.
1. Preparing the bus cables
Velbus recommends a solid core EIB/KNX grade cable with 4x 0,8 mm
diameter. Do not use stranded wire cables or ethernet cables!
Make sure all 4 wires of the bus cable are stripped
8 mm long by using a wire stripping tool .
The Velbus bus cable colors are used in the
following order:
2. Installing the wallbox
Velbus recommends a wallbox with a depth of 50mm.
For example the BATIBOX LEGRAND Ref. 080051 EAN-nr.
3245060800512.
Mount the wallbox into the wall and bring the
EIB cable(s) to the front.

4. Connect the EIB cables with the KNX style connector
Carefully press both sides of the KNX connector protection cab on the Velbus control panel and
turn it towards the top. Then lift the KNX connector block upwards to remove it.
Push all four cables of the EIB/KNX bus cable into the KNX connector, matching the colors.
If you have an arriving and departing cable within the back box, connect both.

5. Mount and setup the Velbus control panel
Connect the Velbus control panel with the KNX connector and close the KNX connector
protection cab to fully secure the KNX connector onto the Velbus control panel.
When your Velbus installation is powered, you should see a green LED next to the PS label.
The blue LED next to the TERM label indicates that the terminator is closed (switch set into the
upper position). This should be the case if your Velbus control module is at the end of a EIB cable.
If the Velbus control module is in series with another device, the terminator should be opened
(switch set into the lower position – blue LED will not be activated).
Tapping the button surfaces on the front of the panel will light up the TX LED (sending CAN bus
data). Using another device in your Velbus installation should light up the RX LED (receiving CAN
bus data). Use these LEDs to troubleshoot if your Velbus control panel is properly connected into
the Velbus network.

Now firmly push the Velbus control panel into the frame, starting from one corner, for ease of
alignment and to focus your pressure onto each of the four small locating pins.
The Velbus control panel should be fully seated against the wall.
Lastly, gently remove the protective film from the Velbus control panel.
The Velbus control panel is now installed and is ready to be configured with the Velbus
configuration software Velbuslink. Go to https://www.velbus.eu/downloads to download the latest
version of Velbuslink.
Only Velbuslink 11.x.x or later is compatible with the VMBELxx-x-20 and VMBGPxx-x-20 series.

6. Removing the Velbus control panel
To remove the Velbus control panel, hold both sides of the panel with your hand and firmly pull
the panel towards you. You may find that starting at one corner is easier, but do not pull
excessively. Do not use tools to pry as they might damage the onboard temperature sensor!
7. Alternative connection technique for the EIB cables.
Since the recommended bus cable is a solid core grade cable with 4x 0,8 mm diameter, it might
be rather sturdy and difficult to mount the Velbus control panel, especially when using an arriving
and departing cable.
To this end, we have included a WAGO push connector for the four
bus cable cores. This connector can be placed inside the wallbox,
allowing you to bring only four wires towards the Velbus control
panel instead of eight.
NB.
Never use excessive force, for example when mounting plates, locating lugs or any cable
connections. Use a release tool on the spring clip connectors if you need to relocate or otherwise
move a cable core.
Excessive force will break a part that can then no longer be returned under warranty!
