  • In general, operating the dimmer without connecting a neutral conductor is possible, although some LED and CFLi light sources require the neutral conductor connection to prevent flickering.
  • For operation without a neutral conductor, the minimum load for light bulbs, HV halogen lamps, Tronic transformers, and wound transformers increases to 50 W.
  • Electronic transformers and ballast devices for LED lamps can be operated with the dimming procedure stated by the manufacturer.
  • The switch-on brightness cannot be saved using a button.
  • The installation adaptor Mini housing 5429 00 is used for mounting in suspended ceilings.
  • If the ambient temperature is higher than 25 °C, the connected load must be reduced.
