DANGER!
Electrical Shock Hazard. Disconnect all power to the drive and wait for the time specified on the warning label before you
remove covers. Check the drive for dangerous voltages before servicing or repair work. If you do work on the drive when it is
energized and there is no cover over the electronic circuits, it will cause serious injury or death from electrical shock. The drive has
internal capacitors that stay charged after you de-energize the drive.
WARNING!
Electrical Shock Hazard. Only let approved personnel install, wire, maintain, examine, replace parts, and repair the
drive. If personnel are not approved, it can cause serious injury or death.
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. If
you do work on the drive when it is energized, it will cause serious injury or death from electrical shock. The drive has internal
capacitors that stay charged after you de-energize the drive.
NOTICE:
Damage to Equipment. When you touch the drive and circuit boards, make sure that you observe correct electrostatic
discharge (ESD) procedures. If you do not follow procedures, it can cause ESD damage to the drive circuitry.
