Notes
If the DALI potentiometer 2117/11 U-500, is used in installations with an existing DALI power
supply, the terminals L and N must not be assigned. The device is then supplied with current
directly from the bus.
Up to 3 DALI potentiometers 2117/11 U-500 and 5 DALI potentiometers 2117 U-500 can be
operated in parallel. In the process, observe the maximum permissible power consumption.
When DALI operating devices, e.g. electronic ballasts, are connected, the specifications of the
respective manufacturer must be observed.
The DALI control line and mains line may lie together in one NYM cable.
Polyphase operation is permissible.
