Auxiliary dimmer unit (ADU)
If the existing installation comprises instruments that
are not of the EasyLink type, then an ADU can be
installed. This means non-EasyLink instrument can
also have the lighting intensity adjusted with the dim-
mer function.

The ADU can be fitted anywhere along the chain of
other EasyLink instruments. See the figure below.
The number of ADUs required depends on how many
filament lamps/LEDs there are in the circuit. One
ADU can supply 5 x 1.2 W (12 V/24 V) filament lamps
or 30 x LEDs, 15 mA (12 V/24 V).
When attaching to the auxilary + supply, an extra
fuse of max 5 A must be used. See positioning in fig-
ure below
