Fasten the cover in place.
Reconnect the device to the supply voltage.
Repeat the process for all other devices.
During the initialisation phase that follows, the device reads the
switch position.
The internal bus voltage supply is deactivated.
Adjusting the switch during operation has no effect on the bus
voltage supply, as the Light Control Box only reads the switch po-
sition during the initialisation phase. This is why you must always
disconnect the device from the supply voltage before you change
the switch position.
You can then connect an external power supply.
4.3.9.2 Connecting an external DALI power supply
The external power supply is connected to a Light Control Box. A parallel
connection makes the voltage supply available to all other Light Control
Boxes.
NOTE!
Using an external DALI power supply and active internal bus voltage supply will
destroy the Light Control Box!
Ensure that the “DALI Power” switch on all Light Control Boxes is
“OFF” (see page page 25)!
