DANGER
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.
WARNING
Electrical Shock Hazard. De-energize the drive and wait 5 minutes minimum until the
Charge LED turns off. Remove the front cover and terminal cover to do work on wiring, circuit boards, and other
parts. Use terminals for their correct function only. Incorrect wiring, incorrect ground connections, and incorrect
repair of protective covers can cause death or serious injury.
WARNING
Electrical Shock Hazard. Correctly ground the drive before you turn on the EMC filter
switch. If you touch electrical equipment that is not grounded, it can cause serious injury or death.
