1.
Shut off power to the drive, wait the appropriate amount of time for voltage to dissipate, then remove the digital
operator (D) and front covers (C, F). Refer to the Quick Start Guide packaged with the drive for directions on
removing the front covers. Cover removal varies depending on drive size.
DANGER! Electrical Shock Hazard. Disconnect all power to the drive and wait at least the amount of time specified on the drive front
cover safety label. After all indicators are off, measure the DC bus voltage to confirm safe level, and check for unsafe voltages before
servicing to prevent electric shock. The internal capacitor remains charged even after the power supply is turned off.
