They also demonstratehow DANLERS Plated time lagswitches (3-wire versions) andDANLERS Slave switches can beincorporated.NOTE: Circuit diagrams 37d and 37eare also applicable to Grid time lagswitches (3 wire versions), see pages40 and 41.37d. Existing 2-way circuitSLloadL N230 VACThese circuit diagrams use the BS7671:2001 harmonised colour codingwith the triple-and-earth colours ofbrown, black and grey for the lines.For clarity all earth wires are omitted.They show the physical connectionswith • or •• as appropriate.They use brown and blue for the lineand neutral feeds to the circuit.They use twin-brown and earth forthe feed to the first 2-way switch.Any unused wires are terminatedwith the x symbol.NOTE:These circuits are onlyrecommendations and thecontractor remains responsiblefor their own work.37e.
