Another major change with the Series 2000 unit is the development of a fit yourself kit. You simply purchase the Series 2000 kit which contains the power unit, fitting instructions, one Red Coupler, six metres of marine wire, joiners, terminals and heat shrink. The above is all that you require to fit the C1 system. ERPS Packaging Box From that point you can purchase additional Blue Capacitive Coupler Packs to suit your needs.
