Connection Methods
The connection techniques used to join the lights to the interconnection cables have been designed to use the minimum of tools. The end result is a joint that will last as long as the lights themselves. Terminal blocks could be used, but over a period of time they will corrode and would still need to be housed in some form of special box to ensure weatherproofing. Our techniques will ensure a totally sealed joint that is benign and can even be immersed in water.
Do not connect to a power supply until each joint has been covered with heat shrink .
Cable Preparation The outer cover of each cable is cut back by 40mm, exposing the inner red and blue cores. These are then stripped back 12mm.

Cable Connections There are two types of cable connection. A type A connection used on all intermediate positions on the interconnecting cable and a type B connection that is only used at the end of a loop. |

In both cases similar colours from each cable are twisted together (ensuring that the red cable is always twisted with the red cable and the blue cable always twisted with the blue) and a ferrule is then threaded over each set of conductors. The crimp can either be flattened using a suitable tool (see Tools & Encapsulating Compounds) or a pair of pliers. Each connection is then inserted into a separate short length of black heat shrink which ensures that all the bare wires are covered. Heat is then to be applied using a hot air gun or cigarette lighter. This will then shrink the sleeve.
All the connections for the complete installation should be made up to this point. It would then be wise to test the system out before encapsulating each joint.
