* Use 75

°C copper wire or equivalent.

IMPORTANT

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:

Line voltage drop (V) =

x wire resistance (

Ω/km) x wire length (m) x current (A) x 10

WARNING

Prior to removing any protective cover or wiring any part of the Drive, remove all power sources, including
main input power and control circuit power. Wait a minimum of 5 minutes after power removal, before
removing any cover. The charge lamp located within the Drive should be off prior to working inside. Even if
the charge lamp is off, one must measure the AC input, output, and DC Bus potential to insure safe levels
prior to resuming work. Failure to adhere to this warning may result in personal injury or death.
