+-- The supply converter is a generic device which can convert from
+-- LV to MV and back, and HV to MV and back.
+-- The machine is configured by the wiring below and above it.
+--
+-- It works like this:
+--   The top side is setup as the receiver side, the bottom as the producer side.
+--   Once the receiver side is powered it will deliver power to the other side.
+--   Unused power is wasted just like any other producer!
