◆ 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 capacitor for the control power supply 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.
Installation, maintenance, inspection and servicing 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.
Do not turn on the power for the EMC Filter Module only.
Failure to comply will result in death or serious injury.
The output terminals remain charged even after the power supply is turned off. Always connect the EMC Filter Module
as shown in the standard connection diagram and turn on the EMC Filter Module according to the diagram.
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-U40302 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
Failure to comply may result in death or serious injury.
Use appropriate equipment for electric leakage circuit breaker (ELCB).
This 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/EN 60755.
