Bulgin Inlet connector datasheet: [1]
Assemble back panel with Bulgin inlet:
CHECK OUT the numbers/letters on the inlet backpanel. Dual pole switch are on A-A, and B-B.
So same cable color on same letter.
cable all together:
DO EARTH CONNECTION TO CHASSIS, THIS IS MANDATORY. EVERY METAL PARTS MUST BE EARTHED!
YOU MUST PLACE A VERY DEATH DANGER ADHESIVE!
