Warning 1. Be sure to apply the specified voltage. Otherwise, malfunction and breakage may be caused. If the applied voltage is lower than the specified, it is possible that the load cannot be moved due to an internal voltage drop of the controller. Please check the operating voltage before use. 2. Do not operate the product beyond the specifications. Otherwise, a fire, malfunction or actuator damage can result. Please check the specifications before use. 3. Install an emergency stop circuit. Please install an emergency stop outside of the enclosure so that it can stop the system operation immediately and intercept the power supply. 4. In order to prevent damage due to the breakdown and the malfunction of the controller and its peripheral devices, a backup system should be established previously by giving a multiple-layered structure or a failsafe design to the equipment, etc. 5. If a danger against the personnel is expected due to an abnormal heat generation, smoking, ignition, etc., of the controller and its peripheral devices, cut off the power supply for the product and the system immediately. Handling Design/Selection Warning 1. Do not touch the inside of the controller and its peripheral devices. It may cause an electric shock or damage to the controller. 2. Do not perform the operation or setting of the product with wet hands. It may cause an electric shock. 3. Product with damage or the one lacking of any components should not be used. It may cause an electric shock, fire, or injury. 4. Use only the specified combination between the electric actuator and controller. It may cause damage to the actuator or the controller. 5. Be careful not to be caught or hit by the workpiece while the actuator is moving. It may cause an injury. 6. Do not connect the power supply or power on the product before confirming the area to which the workpiece moves is safe. The movement of the workpiece may cause an accident. 7. Do not touch the product when it is energized and for some time after power has been disconnected, as it is very hot. It may lead to a burn due to the high temperature. 8. Check the voltage using a tester for more than 5 minutes after power-off in case of installation, wiring and maintenance. It may cause an electric shock, fire, or injury. Handling Warning 9. Static electricity may cause malfunction or break the controller. Do not touch the controller while power is supplied. When touching the controller for maintenance, take sufficient measures to eliminate static electricity. 10. Do not use the product in an area where dust, powder dust, water, chemicals or oil is in the air. It will cause failure or malfunction. 11. Do not use the product in an area where a magnetic field is generated. It will cause failure or malfunction. 12. Do not install the product in the environment of flammable gas, explosive gas and corrosive gas. It could lead to fire, explosion and corrosion. 13. Radiant heat from strong heat supplies such as a furnace, direct sunlight, etc., should not be applied to the product. It will cause failure of the controller or its peripheral devices. 14. Do not use the product in an environment subject to a temperature cycle. It will cause failure of the controller or its peripheral devices. 15. Do not use the product in a place where surges are generated. When there are units that generate a large amount of surge around the product (e.g., solenoid type lifters, high frequency induction furnaces, motors, etc.), this may cause deterioration or damage to the product’s internal circuit. Avoid supplies of surge generation and crossed lines. 16. Do not install the product in an environment under the effect of vibrations and impacts. It will cause failure or malfunction. 17. When a surge generating load such as a relay or solenoid valve is directly driven, use a product that incorporates a surge absorption element. 18. The power supplies should be separated between the controller power and the I/O signal power and both power supplies must not be of “inrush-current limited” type. If the power supply is of “inrush-current limited” type, a voltage drop may occur during the acceleration or deceleration of the actuator.
