Where an Expansion Unit is required to be remote from its preceding unit, plug them together via an Expansion Lead. For example you may wish to keep all the luminaire leads short along a corridor by using more than one unit linked together via Expansion Leads.
Expansion Leads also offer the perfect opportunity for Expansion Units to become part of an interconnection system radiating from a Hub Unit – particularly ideal for the distribution of intelligent control from a central source (i.e DALI bus).
Note: All luminaires will be controlled as one. If using a plug-in control devices it can be plugged into any spare outlet on the run.
Expansion Leads would normally need to be 7-core in order to precisely expand the original units, however if your particular installation does not utilize all 7 poles, for example if your lights are not dimmable, a 5-core expansion lead will suffice.
All Expansion Leads are 16A rated and are available in 1.50mmÂ² LSHF flexible cable or 1.50mmÂ² LSHF cores in 16mmÂ² dia. plastic flexible conduit.
