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, measure 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.
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 serious injury or death.
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.
