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.
WARNING Electrical Shock Hazard. 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.
WARNING Electrical Shock Hazard. Do not use damaged wires, put too much force on the
wiring, or cause damage to the wire insulation. Damaged wires can cause serious injury or death.
WARNING Fire Hazard. Tighten all terminal screws to the correct tightening torque.
Connections that are too loose or too tight can cause incorrect operation and damage to the drive.
Incorrect connections can also cause death or serious injury from fire.
NOTICE Observe correct electrostatic discharge (ESD) procedures when touching the
option. Failure to obey can cause ESD damage to the option circuitry.
NOTICE Damage to Equipment. Do not de-energize the drive while the drive is outputting
voltage. Incorrect equipment sequencing can cause damage to the drive.
