Section Safety
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.
WARNING
Electrical Shock Hazard
Do not operate the drive when covers are missing. Replace covers and shields before you operate
the drive. Use the drive only as specified by the instructions.
Some figures in this section include drives without covers or safety shields to more clearly show the inside of the
drive. If covers or safety shields are missing from the drive, it can cause serous injury or death.
Do not remove covers or touch circuit boards while the drive is energized.
If you touch the internal components of an energized drive, it can cause serious injury or death.
