Termination
Remove the cover.
Generally, only 2 ‘TERM’ terminators must be used in a complete Velbus
®
installation. Usually, this will be on one
module inside the distribution box and on the module which is physically located furthest from the distribution box.
On all other modules, the terminator must be removed.
Remark:
In case of a wiring with multiple branches, only place a termination into a single module in the distribution box and
in the control panel which is the farthest from the distribution box. When communication problems occur, you can
place an extra termination on another branch. It is highly recommended to limit the number of terminations as too
large a number may overload the bus.
