Wiring
There are two wiring systems in a frequency converter: Main circuit and Control circuit.
The Main Circuit terminals are located at the top of the drive. Control Circuit terminals
are located at the bottom of the 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.
