Safety Messages
DANGER
Heed the safety messages in this manual.
Failure to comply will result in death or serious injury.
The operating company is responsible for any injuries or equipment damage resulting from failure to heed the warnings in
this manual.
Electrical Shock Hazard
Before servicing, disconnect all power to the equipment.
The
internal capacitor remains charged even after the power supply is turned off. The charge indicator LED will extinguish
when the DC bus voltage is below 50 Vdc. To prevent electric shock, wait for at least the time specified on the warning label,
once all indicators are OFF, measure for unsafe voltages to confirm the drive is safe prior to servicing.
Failure to comply will result in death or serious injury.
WARNING
Sudden Movement Hazard
System may start unexpectedly upon application of power, resulting in death or serious injury.
Clear
all personnel from the drive, motor and machine area before applying power. Secure covers, couplings, shaft keys and
machine loads before applying power to the drive.
When using DriveWorksEZ to create custom programming, the drive I/O terminal functions change from factory
settings and the drive will not perform as outlined in this manual.
Unpredictable equipment operation may result in death or serious injury.
Take special note of custom I/O programming in the drive before attempting to operate equipment.
Electrical Shock Hazard
Do not attempt to modify or alter the drive in any way not explained in this manual.
Failure to comply could result in death or serious injury.
Yaskawa is not responsible for any modification of the product made by the user. This product must not be modified.
Do not allow unqualified personnel to use equipment.
Failure to comply could result in death or serious injury.
Installation, maintenance, inspection, and service must be performed only by authorized personnel familiar with installation,
adjustment and maintenance of AC drives.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Make sure the protective earthing conductor complies with technical standards and local safety regulations.
Because the leakage current exceeds 3.5 mA in models 4A0414 and larger, IEC/EN 61800-5-1 states that either the power
supply must be automatically disconnected in case of discontinuity of the protective earthing conductor or a protective
earthing conductor with a cross-section of at least 10 mm
2
(Cu) or 16 mm
2
(Al) must be used. Failure to comply may result
in death or serious injury.
Always use appropriate equipment for Ground Fault Circuit Interrupters (GFCIs).
The drive can cause a residual current with a DC component in the protective earthing conductor. Where a residual current
operated protective or monitoring device is used for protection in case of direct or indirect contact, always use a type B GFCI
according to IEC/EN 60755.
Fire Hazard
Do not use an improper voltage source.
Failure to comply could result in death or serious injury by fire.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.
