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, remove the covers before measuring for dangerous voltages to make sure that the
drive is safe. Failure to obey will cause death or serious injury.
1. Loosen the screws on the terminal cover, then pull down on the cover.
CAUTION! Crush Hazard. Only loosen the cover screws. Do not fully remove the cover screws. Make sure that the
terminal covers for larger drives do not fall. Missing cover screws can cause the terminal cover to fall and cause injury.
