Installing the Option
Refer to the following instructions to install the option.
1.
Shut off power to the drive, wait the appropriate amount of time for voltage to
dissipate. Remove the terminal cover screw (C) then remove the terminal cover (D).
Refer to the Quick Start Guide packaged with the drive for directions on removing
the cover. 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.
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 circuitry.
