DANLERS GRTLA EU, GRTLA CB, GRTLA CB ILM, GRTLA EU ILM, GRTLA MK, GRTLA MK ILM Installation guide

  • Hello, I've analyzed the provided document about DANLERS grid time lag switches. This document provides installation notes for GRTLA MK, GRTLA CB, GRTLA EU and their ILM variants. The switches feature adjustable time lags, are suitable for grid mounting and can be wired in parallel. I'm ready to answer your questions about this product.
  • What should I do if I can't get a neutral supply to the switch?
    What to do if time lag switch clicks off but load stays on?
    What depth of wall box is needed for GRTLA MK (ILM)?
    What depth of wall box is needed for GRTLA CB (ILM)?
    What depth of wall box is needed for GRTLA EU (ILM)?
