Installation
In pushbutton mode, the phase of the extension unit 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 (5 cm
minimum).
Rotary pushbutton mode (terminal 2, see Fig. 2)
Up to 5 rotary dimmer extension units 6592 U-xxx can be
connected to allow dimming via the dimmer input (terminal
2).
Data line (terminal D)
To allow switching and dimming via the data line at
terminal D, the dimmer can be operated through control
modules (e.g. 6597, 6197/11-xxx or 6997/60-xxx).
If a control module is connected, the on-site
operation and the extension units are
automatically locked.
