3.1
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.
Make sure that the protective ground wire conforms to technical standards and local safety
regulations. The IEC/EN 61800-5-1:2007 standard specifies that you must wire the power supply to
automatically de-energize when the protective ground wire disconnects. You can also connect a
protective ground wire that has a minimum cross-sectional area of 10 mm
2
(copper wire) or 16 mm
2
(aluminum wire).
If you do not obey the standards and regulations, it can cause serious injury or death. The leakage current of the
drive will be more than 3.5 mA in drive models 4414 to 4720.
The drive can cause a residual current with a DC component in the protective earthing conductor.
When a residual current operated protective or monitoring device prevents direct or indirect
contact, always use a type B Ground Fault Circuit Interrupter (GFCI) as specified by IEC/EN 60755.
If you do not use the correct GFCI, it can cause serious injury or death.
Do not wear loose clothing or jewelry when you do work on the drive. Tighten loose clothing and
remove all metal objects, for example watches or rings.
Loose clothing can catch on the drive and jewelry can conduct electricity and cause serious 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.
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.
Do not modify the drive body or drive circuitry.
Modifications to drive body and circuitry can cause serious injury or death, will cause damage to the drive, and will
void the warranty. Yaskawa is not responsible for modifications of the product made by the user.
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.
Tighten screws at an angle in the specified range shown in this manual.
If you tighten the screws at an angle not in the specified range, you can have loose connections that can cause
damage to the terminal block or start a fire and cause serious injury or death.
