The supply uses the same type of 2x32 pin connector as the other Schneiderware boards, however, the supply is '''NOT''' intended to be plugged into the [[ECB Bus]] sockets, instead, it should be wired to the 7 soldering points on the [[Schneiderware Basisplatine]].
Namely, it connects to the three GND pins, and the 5V, and -/+12V pins. The seventh pin, "AC", is left unused (it's been intended for rechargeable "ACCU" batteries, but the later RTC and SRAM projects contained their own batteries, and didn't use the "AC" supply).
The CPC's internal +5V supply should be disconnected when connecting the external power-supply, otherwise something terrible might happen (for example, when one supply tries to output a few more volts than the other, or so).
