I need to wire in a replacement power supply for a hobby appliance and don't understand the markings on the supply here is a picture of the terminals

Which side is the AC input and which terminal is which, GND is obvious. then the outputs N and L ?? Not nomenclature that I am used to seeing. It is 120vac in 24vdc out.

Normally L and N refers to "line" and "neutral" on the 120 volt side. The "+" sign on the left side indicates the 24 volt side, in AC you don't have + or -, you have line and neutral. On DC you have + and -.

based on what you are saying then from the power cord, the black goes to L, the white goes to N, Does the green go to GND or FG?

Green from power cord would go to the frame ground (FG). Your 24VDC would come from the + terminal and the GND terminal on the left.

"FG" is "Frame Ground", referring to the ground connection to the metal chassis of the power supply. Should be connected to the mains earth via the green or green-and-yellow conductor in the mains cable (power cord).
