3.1 Safety Precautions
WARNING
Do not put flammable or combustible materials on top of the drive and do not install the drive
near flammable or combustible materials. Attach the drive to metal or other noncombustible
material.
Failure to obey can cause death or serious injury.
Tighten screws against the bit 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.
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.
Electrical Shock Hazard
Do not make changes to the drive body or drive circuitry.
Failure to obey can cause death or serious injury and will void warranty. The manufacturer is not responsible for
changes to the product made by the user.
Only let authorized persons install, wire, maintain, examine, replace parts, and repair the drive.
Failure to obey can cause death or serious injury.
Do not remove covers or touch circuit boards while the drive is energized.
Failure to obey can cause death or serious injury.
Do not work on the drive or around the drive while wearing loose clothing or jewelry. Tighten
loose clothing and remove all metal objects such as watches or rings.
Failure to obey can cause death or serious injury.
Always use a type B Residual Current Monitor/Residual Current Device (RCM/RCD) where a
residual current operated protective or monitoring device protects against direct or indirect
contact as specified by IEC/EN 60755 The drive can cause a residual current with a DC
component in the protective earthing conductor.
Failure to obey can cause death or serious injury.
The leakage current of the drive will be more than 3.5 mA. The IEC/EN 61800-5-1: 2007 standard
specifies that users must wire the power supply to automatically turn off when the protective
ground wire disconnects. Users 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).
Failure to obey these standards can cause death or serious injury.
3
Ground the neutral point on the power supply to comply with the EMC Directive before turning
on the EMC filter or if there is high resistance grounding.
If the EMC filter is switched ON without the neutral point being grounded or if there is high resistance
grounding, it can cause death or serious injury.
Do not operate equipment when covers are missing. Some figures in this section include drives
without covers or safety shields to more clearly show the inside of the drive. Replace covers
and shields before operation. Use drives only as specified by the instructions.
Failure to obey can cause death or serious injury.
CAUTION
Crush Hazard
Do not hold the drive by the front cover or terminal cover. Tighten the screws correctly before
moving the drive.
Failure to obey can cause minor to moderate injury.
