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.
