1.1.1.47
In order to ensure that the halogen lamps have the
same degree of brightness over the entire correcting
range from bright to dark, transformers with the same
secondary voltage and the same rated power should be
used.
Pushbutton Mode
With pushbutton mode, the phase of the extension and
the phase of the supply voltage must be the same.
With pushbutton extensions, the lighting glow lamp
should not be connected with parallel contacts (use
pushbutton with N connection).
When laying lines, ensure that there is sufficient space
between the control and load lines (min. 5 cm).

extension unit is 100 m.
