Just in the process of fitting some lights at the bottom of the garden and have got a Time Guard Weathersafe programmable timer. The actual timer is a "Theben" TR 610 Top but I am not sure how to wire it in respect of incoming power and outgoing to the lights as the diagram just shows N L1 & L2. I have found a pdf with the wiring diagram if anyone can comment. www.prokontrol.com/Fr/Catalogue/MISC.pdf
