5 Installation Procedure
◆
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.
