DANGER! Electrical Shock Hazard. Electrical Shock Hazard. Do not examine, connect, or disconnect wiring on an energized
drive. Before servicing, disconnect all power to the equipment and wait for the time specified on the warning label at a minimum.
The internal capacitor stays charged after the drive is de-energized. The charge indicator LED extinguishes when the DC bus
voltage decreases below 50 Vdc. When all indicators are OFF, measure for dangerous voltages to make sure that the drive is
safe. If you do work on the drive when it is energized, it will cause serious injury or death from electrical shock.
