Warning

Caution – Rotating Parts!

•

The system includes a motor. Touching the rotating shaft could cause high-temperature

burns or injury.

Always insert plugs, connectors, and cables securely, and confirm that they are fully inserted.

•

Incomplete connections could cause fire, burns, electric shock, or injury.

Use the power supply apparatus specified in the manual.

•

Failure to do so could cause fire, burns, electric shock, injury, or malfunction.

Disconnect the power supply and unplug all cables when the system will not be used for a

period of time or when moving the system.

•

Failure to do so could cause fire, burns, electric shock, or malfunction.

•This will protect the system against damage due to lightning.

Use a mechanism (switch, outlet, etc.) located within reach to turn off (disconnect) the power

supply.

•In case of emergency, it may be necessary to cut off the power supply quickly.

Turn off the power supply immediately if you notice abnormal odor, smoke, abnormal sound,

or overheating.

•

Continuing to use the system in an abnormal condition could cause fire, burns, or electric

shock.

Do Not Disassemble, Modify, or Repair!

•

Failure to do so could cause fire, burns, electric shock, injury, or malfunction.

Do not use the product for any purpose other than initial evaluation of motor control in a

testing room or lab.

Do not integrate the product or any part of it into other equipment.

Do not insert or remove cables or connectors when the product is powered on.

•

The product has no safety case.

•

Failure to observe the above could cause fire, electric shock, burns, or malfunction.

•The product may not perform as expected if used for other than its intended purpose.

Caution

Caution – Hot!

•

The motor gets hot. Touching it could cause high-temperature burns.

Follow the procedure specified in the manual when powering the system on or off.
