YASKAWA
TOEPC71061687B Powerlink Option Installation Manual
WARNING
Fire Hazard. Do not connect power supply wiring to drive output terminals U/T1, V/T2, and
W/T3. Connect power supply wiring to main circuit input terminals R/L1, S/L2, and T/L3. Failure to obey can
cause death or serious injury.
WARNING
Crush Hazard. Only approved personnel can operate a crane or hoist to move the drive.
Failure to obey can cause death or serious injury from falling equipment.
WARNING
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. Yaskawa is not responsible for changes to the
product made by the user.
WARNING
Electrical Shock Hazard. Only let authorized persons install, wire, maintain, examine,
replace parts, and repair the drive. Failure to obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. Always ground the motor-side grounding terminal. Contacting the
motor case can cause death or serious injury from incorrect equipment grounding.
WARNING
Electrical Shock Hazard. 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.
WARNING
Electrical Shock Hazard. The leakage current of the drive will be more than 3.5 mA in
some drive models. 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.
WARNING
Sudden Movement Hazard. Remove all persons and objects from the area around the
drive, motor, and load before starting Auto-Tuning. The drive and motor can start suddenly during Auto-Tuning
and cause death or serious injury.
WARNING
Sudden Movement Hazard. Remove all persons and objects from the area around the
drive, motor, and machine area and attach covers, couplings, shaft keys, and machine loads before energizing
the drive. Failure to obey can cause death or serious injury.
WARNING
Fire Hazard. Do not use the main circuit power supply (Overcurrent Category III) at
incorrect voltages. Make sure that the drive rated voltage aligns with the power supply voltage before energizing
the drive. Failure to obey can cause death or serious injury.
WARNING
Fire Hazard. 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.
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.
WARNING
Fire Hazard. Tighten screws against the bit at an angle in the specified range described in
this manual. Tightening screws at an angle outside of the specified range can cause damage the terminal block or
start a fire if the connection is loose.
WARNING
Crush Hazard. Use a lifting mechanism made to move large drives when necessary.
Failure to obey can cause death or serious injury from falling equipment.
WARNING
Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. Failure to
obey can cause death or serious injury.
WARNING
Electrical Shock Hazard. 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.
WARNING
Electrical Shock Hazard. Ground the neutral point on the power supply of drive models
2xxxB/C and 4xxxA/B/C 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.
