Important information

Caution!
Work on the 230V supply system may only be
performed by authorised and qualified electricians.
To achieve the same brightness level of the halogen lamps
over the entire adjusting range from bright to dark,
electronic transformers with the same secondary voltage
and the same power should be used.
The dimmer heats up during operation because part of the
connected load is lost and converted into heat. The
specified rated power is designed for dimmer installation in
a solid masonry wall. When installing the dimmer in a wall
made of gas concrete, wood or plasterboard, the maximum
connected load must be reduced by 20% (see also fig. 3).
This equals a power of 80% = 336 W. Reducing the
connected load is always necessary when several
dimmers are installed one beside or below the other or
when other heat sources cause additional heating.
