Abstract
A diode-configured power supply interface circuit prevents inadvertent miswiring of power supply leads to wrong polarity voltages of either primary or auxiliary DC supply voltages from triggering the operation of a circuit protection device installed in the power supply path of a telecommunication circuit. It also indicates whether the device's power terminals are properly connected to a power source, so that if inadvertently reversed, the wires can be properly reconnected, and thereby provide for delivery of power from either power source, as required.
