Shut off power to the drive, wait the appropriate amount of time for voltage to
dissipate, then remove the digital operator (B) and front covers (A, D). Front cover
removal varies by model.
DANGER! Electrical Shock Hazard. Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury. Before installing the option, disconnect all
power to the drive. The internal capacitor remains charged even after the power supply is turned
off. The charge indicator LED will extinguish when the DC bus voltage is below 50 Vdc. To prevent
electric shock, wait at least five minutes after all indicators are off and measure the DC bus voltage
level to confirm safe level.
NOTICE: Damage to Equipment. Observe proper electrostatic discharge procedures (ESD) when
handling the option, drive, and circuit boards. Failure to comply may result in ESD damage to
