* Use 75°C copper wire or equivalent.
Determine the wire size for the main circuit so that line voltage drop is within 2% of the rated voltage. Line
voltage drop is calculated as follows:
IMPORTANT
Line voltage drop (V) =
Prior to removing any protective cover or wiring any part of the Drive, remove all power sources, including
