  • Page 5: General Precautions

    Make sure that these protective covers are on the product before use. Consult your OMRON representative when using the product after a long period of storage. WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock.
  • Page 6: Installation Precautions

    Transportation Precautions Caution 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. Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc- tion.
  • Page 7 Caution Install external 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 sup- ply voltage. An incorrect power supply may result in fire, injury, or malfunction. Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual.
  • Page 8 WARNING Provide a separate emergency stop switch because the STOP Key on the Operator is valid only when function settings are performed. Not doing so may result in injury. WARNING Be sure confirm that the RUN signal is turned OFF before turning ON the power supply, resetting the alarm, or switching the LOCAL/REMOTE selector.
  • Page 9 Warnings for UL/cUL Marking • Do not connect or disconnect wiring, or perform signal checks while the power supply is turned ON. • The Inverter internal capacitor is still charged even after the power supply is turned OFF. To prevent electrical shock, disconnect all power before servicing the Inverter.
  • Page 10 • This parameter is used to set the electric thermal characteristics of the motor to be connected. • Set the parameter according to the motor. • If a single Inverter is connected to more than one motor, set the parameter to 2 for no protection. The parameter is also disabled by setting n036 for rated motor current to 0.0.

    Maintenance Operations Chapter 4 Protective and Diagnostic Functions 4-1-1 Fault Detection (Fatal Errors) The Inverter will detect the following faults if the Inverter or motor burns or the internal circuitry of the Inverter malfunctions. When the Inverter detects a fault, the fault code will be displayed on the Digital Operator, the fault contact output will operate, and the Inverter output will be shut off causing the motor to coast to a stop.
