- Do not touch the heat sink, which heats up during the inverter operation. Otherwise, you run the risk
of burn injury.
- The inverter allows you to easily control the speed of motor or machine operations. Before operating
the inverter, confirm the capacity and ratings of the motor or machine controlled by the inverter.
Otherwise, you run the risk of injury.
- Install an external brake system if needed. Otherwise, you run the risk of injury.
- When using the inverter to operate a standard motor at a frequency of over 60 Hz, check the
allowable motor speeds with the manufacturers of the motor and the machine to be driven and obtain
their consent before starting inverter operation. Otherwise, you run the risk of damage to the motor
and machine.
- During inverter operation, check the motor for the direction of rotation, abnormal sound, and
vibrations. Otherwise, you run the risk of damage to the machine driven by the motor.
- HIGH VOLTAGE: Dangerous voltage exists even after the Safe Stop is activated. It does NOT mean
that the main power has been removed.
4. Maintenance, inspection, and parts replacement
- Before inspecting the inverter, be sure to turn off the power supply and wait for 10 minutes or more.
Otherwise, you run the risk of electric shock. (Before inspection, confirm that the Charge lamp on
the inverter is off.)
- Commit only a designated person to maintenance, inspection, and the replacement of parts. (Be
sure to remove wristwatches and metal accessories, e.g., bracelets, before maintenance and
inspection work and to use insulated tools for the work.) Otherwise, you run the risk of electric
shock and injury.
- Do not rely upon the STO feature to disconnect the power from the motor circuit. It is required isolate
the supply before any maintenance is carried out on the motor circuit. See Functional Safety for
detail.
5. Others
- Do not discard the inverter with household waste. Contact an industrial waste management company
in your area who can treat industrial waste without polluting the environment.
- Never modify the inverter. Otherwise, you run the risk of electric shock and injury.
6. When using Safe Stop Function
- When using Safe Stop function, make sure to check whether the safe stop function properly works
when installation (before starting operation). Please carefully refer to Functional Safety for detail.
