When installing the galvanic separation of the electric circuits
must be ensured. It is necessary to comply with the German
standard DIN VDE 0834.
An appropriate dimmable ballast is required to use the dim-
ming, e.g. OSRAM DALI.

When using a mechanical relay a freewheeling
diode must be connected (e.g. 1N4002)
directly at the relay connector.
