3 Operation and Test Run
3 - 2
High-function General-purpose Inverter 3G3RX-V1 User’s Manual (I578-E1)
• Be sure to confirm the permissible range of motors and machines before operation because the
inverter speed can be changed easily from low to high.
• Provide a separate holding brake if necessary.
• If a parameter is set incorrectly when starting up, adjusting, maintaining, or replacing, an unexpected
operation may occur. Perform the operation after enough confirmation.
• When using DriveProgramming, confirm that the program data is downloaded normally before
starting the operation.
Do not change wiring and slide switches (SW1), put on or take off Operator and optional devices,
replace cooling fans while the input power is being supplied. Doing so may result in a serious injury
due to an electric shock.
Do not remove the terminal cover during the power supply and 10 minutes after the power shut off.
Doing so may result in a serious injury due to an electric shock.
Do not operate the Operator or switches with wet hands.
Doing so may result in a serious injury due to an electric shock.
Inspection of the inverter must be conducted after the power supply was turned off. Not doing so
may result in a serious injury due to an electric shock.
The main power supply is not necessarily shut off even if the emergency shut off function is
activated.
Do not touch the inverter fins, braking resistors and the motor, which become too hot during the
power supply and for some time after the power shut off.
Doing so may result in a burn.
Take safety precautions such as setting up a molded-case circuit breaker (MCCB) that matches the
inverter capacity on the power supply side. Not doing so might result in damage to property due to
the short circuit of the load.
