General Precautions

Observe the following precautions when using the VARISPEED Inverters and

peripheral devices.

This manual may include illustrations of the product with protective covers

removed in order to describe the components of the product in detail. Make

sure that these protective covers are on the product before use.

Consult your OMRON-YASKAWA representative when using the product after

a long period of storage.

Do not touch the inside of the Inverter. Doing so may result in electrical shock.

Operation, maintenance, or inspection must be performed after turning OFF

the power supply, confirming that the CHARGE indicator (or status indicators)

are OFF, and after waiting for the time specified on the front cover. Not doing

so may result in electrical shock.

Do not damage, pull on, apply stress to, place heavy objects on, or pinch the

cables. Doing so may result in electrical shock.

Do not touch the rotating parts of the motor under operation. Doing so may

result in injury.

Do not modify the product. Doing so may result in injury or damage to the

product.

Do not store, install, or operate the product in the following places. Doing so

may result in electrical shock, fire or damage to the product.

• Locations subject to direct sunlight.

• Locations subject to temperatures or humidity outside the range specified

in the specifications.

• Locations subject to condensation as the result of severe changes in

temperature.

• Locations subject to corrosive or flammable gases.

• Locations subject to exposure to combustibles.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to exposure to water, oil, or chemicals.

• Locations subject to shock or vibration.

Do not touch the Inverter radiator, regenerative resistor, or Servomotor while

the power is being supplied or soon after the power is turned OFF. Doing so

may result in a skin burn due to the hot surface.

Do not conduct a dielectric strength test on any part of the Inverter. Doing so

may result in damage to the product or malfunction.

Take appropriate and sufficient countermeasures when installing systems in

the following locations. Not doing so may result in equipment damage.

• Locations subject to static electricity or other forms of noise.

• Locations subject to strong electromagnetic fields and magnetic fields.

• Locations subject to possible exposure to radioactivity.

• Locations close to power supplies.
