YASKAWA LA500 Installation And Operation Instruction Manual page 11

Note:
Failure to obey the safety messages in the manual can cause serious injury or death. Yaskawa is not responsible for
injuries or damage to equipment caused by ignoring the safety messages.
• Read this manual carefully when mounting, operating, and repairing AC drives.
• Obey all warnings, cautions, and notices.
• Approved personnel must perform all work.
• Install the drive according to this manual and local codes.
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
Fire Hazard. Do not connect main power supply wiring to drive motor terminals U/T1, V/
T2, and W/T3. Connect main power supply wiring to main circuit input terminals R/L1, S/L2, and T/L3. Incorrect
wiring can cause serious injury or death from fire.
WARNING
Electrical Shock Hazard. 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.
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. Always ground the motor-side grounding terminal. If you do not
ground the equipment correctly, it can cause serious injury or death if you touch the motor case.
WARNING
Electrical Shock Hazard. 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.
WARNING
Sudden Movement Hazard. Before you do Auto-Tuning, remove all personnel and objects
from the area around the drive, motor, and load. The drive and motor can start suddenly during Auto-Tuning and
cause serious injury or death.
WARNING
Sudden Movement Hazard. Remove all personnel and objects from the area around the
drive, motor, and machine and attach covers, couplings, shaft keys, and machine loads before you energize the
drive. If personnel are too close or if there are missing parts, it can cause serious injury or death.
WARNING
Damage to Equipment. Do not apply incorrect voltage to the main circuit of the drive.
Operate the drive in the specified range of the input voltage on the drive nameplate. Voltages that are higher than
the permitted nameplate tolerance can cause damage to the drive.
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. Flammable and combustible materials can start a fire and 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.
WARNING
Fire Hazard. 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.
WARNING
Electrical Shock Hazard. Do not cause a short circuit on the drive output circuit. A short
circuit on the output can cause serious injury or death.
WARNING
Electrical Shock Hazard. When there is a DC component in the protective earthing
conductor, the drive can cause a residual current. When a residual current operated protective or monitoring
device prevents direct or indirect contact, always use a type B Residual Current Monitor/Residual Current Device
(RCM/RCD) as specified by IEC/EN 60755. If you do not use the correct RCM/RCD, it can cause serious injury or
death.
