JANCD-YIO21 Yaskawa

The Bypass includes branch circuit protection and is suitable for use on a circuit capable of delivering not more than 65,000

RMS symmetrical amperes (100,000 RMS with 100 kA Input Circuit Breaker option (PM) added), 208 Vac maximum and

480 Vac maximum.

Description:

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.

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.

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 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 mm2

 (Cu) or 16 mm2

 (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.
