My DENTRON MLA-2500B uses 3 wires AC input cord,
2 wires for AC 234V and the third wire is for chassis GND
which is connected to the GND pin out of 3 pin in a wall
Regarding to 117V which is fed to cooling fan, primary
connection of the xfmr (I mean the center tap of the xfmr)
gives 117V internally. Therefore the AMP does not require
line neutral connection form the wall outlet.
I am using a 3 blades AC plug with twist lock mechanism
against sudden disconnection due to unexpected pulling.
