Wiring

There are two wiring systems in an AFD: Main Circuit and Control Circuit. The Main
Circuit terminals are located at the top of the drive. Control Circuit terminals are located
bottom of drive, Both terminal blocks are covered by the plastic housing. Lift the
hinged portion of the housing to gain access to the terminals. Make sure power is
removed before making any connections. Connect wires to the terminals according to
the diagram below. When no connections are made to the control terminals, the drive is
operated by the Digital Keypad/Display.
