◆ 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
Do not install, wire, maintain, or inspect the product or replace parts while the power supply is turned on.
Failure to comply will result in death or serious injury.
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 converter before touching any
components.
W ARNING
Sudden Movement Hazard
System may start unexpectedly upon application of power, resulting in death or serious injury.
Clear all personnel from the converter, drive, motor and machine area before applying power to the converter. Secure
covers, couplings, shaft keys and machine loads.
Electrical Shock Hazard
Do not attempt to modify or alter the converter 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 perform work on the converter.
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 converters.
Do not remove covers or touch circuit boards while the power is on.
Failure to comply could result in death or serious injury.
Always use a ground wire that complies with technical standards on electrical equipment and minimize the
length of the ground wire.
Improper equipment grounding may cause dangerous electrical potentials on equipment chassis, which 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 model 4A0630, 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 a type B ground fault circuit interrupter GFCI according to IEC/EN 60755 when a protective
residual current monitor/detection device is installed for indirect or direct shock hazard protection.
The converter can cause a residual current with a DC component in the protective earthing conductor.
