People installing DTSC-200A , easYgen-400, -600, -800, - 1400, -1600 , - 1700 & -1800 controls in an 400, 440, 480 VAC voltage application are sometimes confused , if they are seeing this pic in instruction manual :

To be compliant to UL6200 standard, we have to limit Line to Line voltages to maximum 300VAC.

Used voltage sensing connectors have UL up to 300V Line to Line (E-60425-19931013).

If you built a control panel which is not according to UL6200 you can go up to 480VAC Line to Line as described in manuals.
