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.

Transportation Precautions
Do not hold by front cover or panel , instead, hold by the radiation fin (heat
sink) while transporting the product. Doing so may result in injury.
Do not pull on the cables. Doing so may result in damage to the product or
malfunction.
Use the eye-bolts only for transporting the Inverter. Using them for
transporting the machinery may result in injury or malfunction.
Installation Precautions
Provide an appropriate stopping device on the machine side to secure safety.
(A holding brake is not a stopping device for securing safety.) Not doing so
may result in injury.
Provide an external emergency stopping device that allows an instantaneous
stop of operation and power interruption. Not doing so may result in injury.
Be sure to install the product in the correct direction and provide specified
clearances between the Inverter and control panel or with other devices. Not
doing so may result in fire or malfunction.
Do not allow foreign objects to enter inside the product. Doing so may result in
fire or malfunction.
Do not apply any strong impact. Doing so may result in damage to the product
or malfunction.
Wiring Precautions
Wiring must be performed only after confirming that the power supply has
been turned OFF. Not doing so may result in electrical shock.
Wiring must be performed by authorized personnel. Not doing so may result in
electrical shock or fire.
Be sure to confirm operation only after wiring the emergency stop circuit. Not
doing so may result in injury.
Always connect the ground terminals to a ground of 100 W or less for the
200V AC class, or 10 W or less for the 400-V AC class. Not connecting to a
proper ground may result in electrical shock.
Install external breakers and take other safety measures against short-
circuiting in external wiring. Not doing so may result in fire.
Confirm that the rated input voltage of the Inverter is the same as the AC
power supply voltage. An incorrect power supply may result in fire, injury, or
malfunction.
Connect the Braking Resistor and Braking Resistor Unit as specified in the
manual. Not doing so may result in fire.
Be sure to wire correctly and securely. Not doing so may result in injury or
damage to the product.
Be sure to firmly tighten the screws on the terminal block. Not doing so may
result in fire, injury, or damage to the product.
Do not connect an AC power to the U, V, or W output. Doing so may result in
damage to the product or malfunction.
