3Operation 3 Operation Safety Information „ Operation and Adjustment •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. 3-1 WARNING Do not change wiring and slide switches (SW1), put on or take off Digital 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 block cover during the power supply and 10 minutes after the power shutoff. Doing so may result in a serious injury due to an electric shock.
Do not operate the Digital 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 has been 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 shutoff function is activated. CAUTION 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 shutoff. 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.
