Control Terminals - GE AF-650 GP Design Manual

Installation of field installed 24 Volt external DC Supply option module (OPC24VPS)
Torque: 0.5 - 0.6 Nm (5 in-lbs)
Screw size: M3
24 VDC external supply can be used as low-voltage supply to the control card and any I/O or network option cards installed. This enables full operation of the
Keypad (including parameter setting) without connection to mains. Please note that a warning of low voltage will be given when 24 VDC has been connected;
however, there will be no tripping.
Use 24 VDC supply of type PELV to ensure correct galvanic isolation (type PELV) on the control terminals of the frequency converter.
