Interference Suppression - ABB Busch-Dimmer 6593 U-500 Manual Del Usuario

Important Information
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).
- The maximum line length of the pushbutton extension
unit is 100 m.
- Changing the conductor routing of existing two-way
circuits and intermediate switch circuits is not
necessary.

Interference Suppression

A novel electronic interference suppressor replaces the
former conventional interference suppression choke.
Consequently, this is a "low-noise" dimmer.
