Be sure to read before handling. Refer to page 469 for Safety Instructions and the Operation Manual for Electric Actuator Precautions. Please download it via our website, http://www.smcworld.com Design/Selection Warning 1. Use the specified voltage. If the applied voltage is higher than the specified voltage, malfunction and damage to the driver may result. If the applied voltage is lower than the specified voltage, there is a possibility that the load cannot be moved due to internal voltage drop. Check the operating voltage prior to start. Also, confirm that the operating voltage does not drop below the specified voltage during operation. 2. Do not use the products outside the specifications. Otherwise, fire, malfunction or damage to the driver/actuator can result. Check the specifications prior to use. 3. Install an emergency stop circuit. Install an emergency stop outside the enclosure in easy reach to the operator so that the operator can stop the system operation immediately and intercept the power supply. 4. To prevent danger and damage due to a breakdown or malfunction of these products, which may occur at a certain probability, a backup system should be arranged in advance by using a multiple-layered structure or by making a fail-safe equipment design, etc. 5. If there is a risk of fire or personal injury due to abnormal heat generation, sparking, smoke generated by the product, etc., cut off the power supply from this product and the system immediately. Handling Warning 1. Never touch the inside of the driver and its peripheral devices. Otherwise, electric shock or failure can result. 2. Do not operate or set up this equipment with wet hands. Otherwise, electric shock can result. 3. Do not use a product that is damaged or missing any components. Electric shock, fire or injury can result. 4. Use only the specified combination between the electric actuator and driver. Otherwise, it may cause damage to the driver or to the other equipment. 5. Be careful not to touch, get caught or hit by the workpiece while the actuator is moving. An injury can result. 6. Do not connect the power supply or power up the product until it is confirmed that the workpiece can be moved safely within the area that can be reached by the workpiece. Otherwise, the movement of the workpiece may cause an accident. 7. Do not touch the product when it is energized and for some time after the power has been disconnected, as it is very hot. Otherwise, it may cause burns due to the high temperature. 8. Check the voltage using a tester at least 5 minutes after power-off when performing installation, wiring and maintenance. Otherwise, electric shock, fire or injury can result. Handling Warning 9. Static electricity may cause a malfunction or damage the driver. Do not touch the driver while power is supplied to it. Take sufficient safety measures to eliminate static electricity when it is necessary to touch the driver for maintenance. 10. Do not use the products in an area where they could be exposed to dust, metallic powder, machining chips or splashes of water, oil or chemicals. Otherwise, a failure or malfunction can result. 11. Do not use the products in a magnetic field. Otherwise, a malfunction or failure can result. 12. Do not use the products in an environment where flammable, explosive or corrosive gases, liquids or other substances are present. Otherwise, fire, explosion or corrosion can result. 13. Avoid heat radiation from strong heat sources, such as direct sunlight or a hot furnace. Otherwise, it will cause a failure to the driver or its peripheral devices. 14. Do not use the products in an environment with cyclic temperature changes. Otherwise, it will cause a failure to the driver or its peripheral devices. 15. Do not use the products in an environment where surges are generated. Devices (solenoid type lifters, high frequency induction furnaces, motors, etc.) that generate a large amount of surge around the product may lead to deterioration or damage to the internal circuits of the products. Avoid supplies of surge generation and crossed lines. 16. Do not install these products in a place subject to vibration and impact. Otherwise, a malfunction or failure can result. 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. Mounting Warning 1. Install the driver and its peripheral devices on fireproof material. Direct installation on or near flammable material may cause fire. 2. Do not install these products in a place subject to vibration and impact. Otherwise, a malfunction or failure can result. 3. The driver should be mounted on a vertical wall in a vertical direction. Also, do not cover the driver’s suction/exhaust ports. 4. Install the driver and its peripheral devices on a flat surface. If the mounting surface is not flat or uneven, excessive force may be applied to the housing and other parts resulting in a malfunction. Series LECS�ｮ Specific Product Precautions 1 437
