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.
NOTICE:
Damage to Equipment. Observe correct electrostatic discharge (ESD) procedures when touching
the option, drive, and circuit boards. Failure to obey can cause ESD damage to the drive circuitry.
