Should you wish to construct your own custom power cable, Elo highly recommends using AMP
After connecting the power cable to the monitor, but before applying power, ensure that the power cable’s black or brown wire connects to the monitor’s brown wire; the power cable’s green wire connects to the monitor’s green wire; and the power cable’s white or blue wire connects to the monitor’s blue wire.
Note: The cable used must include a green (earth ground) wire, it must be 18AWG (or larger), and it should be rated SVT 105C 600V (or better).
