Safety Messages

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.
Do not connect or disconnect wiring while the power is on.
Failure to comply will result in death or serious injury.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply
is turned off. After shutting off the power, wait for at least the amount of time specified on the drive before touching any
components.
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.
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.
Maintenance, inspection, and replacement of parts 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 CIMR-Ao4A0414 and larger, IEC 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
in death or serious injury.
Always use appropriate equipment for electric leakage circuit breakers (ELCB).
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 an ELCB of
type B according to IEC 60755.
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.
