5. Wiring
The ballast circuit can be connected as shown in Figure 10. If no dimming is required, the
dimmer input must be left floating.

Fig 10. Wiring diagram
The earth/chassis connection must be connected to the earth tag J3 shown in Figure 13.
There is no provision for an earth connection on the mains connector. If a metal fixture is
used, it must also be connected to the earth tag J3.
6. Dimming without external voltage source
The ballast circuit is designed to be dimmed with a voltage source from 1 V to 10 V DC.
However, it is possible to dim with an external potentiometer of 470 k. This function is
intended for demonstration purposes only. The potentiometer must be connected to pin 1
(grey wire) and pin 2 (violet wire) of connector J1.
