Be sure to confirm operation only after wiring the emergency stop circuit. Not
doing so may result in injury.
Required
Always connect the ground terminals to a ground of 100 Ohm or less for 200-
V AC class or 10 Ohm or less for the 400-V class. Not connecting to a proper
ground may result in electrical shock or fire.
Caution
Install external circuit breakers and take other safety measures against short-
circuiting in external wiring. Not doing so may result in fire.
Caution
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.
Caution
Connect the Braking Resistor or Braking Resistor Unit as specified in the man-
ual. Not doing so may result in fire.
Caution
Be sure to wire correctly and securely. Not doing so may result in injury or
damage to the product.
Caution
Be sure to firmly tighten the screws on the terminal block. Not doing so may
result in fire, injury or damage to the product.
Caution
Do not connect an AC power source to the U,V,W output. Doing so may result
in damage to the product or malfunction.
Caution
Do not connect a load to the machine during auto-tuning. Not doing so may
result in equipment damage.
