Alterations made to this product may lead to a loss of durability and damage to the product, which can lead to human injury and damage to other equipment and machinery. • When an external guide is used, connect the moving parts of the product and the load in such a way that there is no interference at any point within the stroke. Do not scratch or dent the sliding parts of the table or mounting face etc., by striking or holding them with other objects. The components are manufactured to precise tolerances, so that even a slight deformation may cause faulty operation or seizure. • Do not use the product until you verify that the equipment can be operated correctly. After mounting or repair, connect the power supply to the product and perform appropriate functional inspections to check it is mounted correctly. • When attaching to the work piece, do not apply strong impact or large moment. If an external force over the allowable moment is applied, it may cause looseness in the guide unit, an increase in sliding resistance or other problems. • Maintenance space Allow sufficient space for maintenance and inspection. 2.4 Handling Warning • Do not touch the motor while in operation. The surface temperature of the motor can increase to approx. 90°C to 100°C due to operating conditions. Energizing alone may also cause this temperature increase. As it may cause burns, do not touch the motor when in operation. • If abnormal heating, smoking or fire, etc. occurs in the product, immediately turn off the power supply. • Immediately stop operation if abnormal operation noise or vibration occurs. If abnormal operation noise or vibration occurs, the product may have been mounted incorrectly. Unless operation of the product is stopped for inspection, the product can be seriously damaged. • Never touch the rotating part of the motor or the moving part of the actuator while in operation. There is a serious risk of injury. • When installing, adjusting, inspecting or performing maintenance on the product, controller and related equipment, be sure to turn off the power supply to each of them. Then, lock it so that no one other than the person working can turn the power on, or implement measures such as a safety plug. • In the case of the actuator that has a servo motor (24VDC), the “motor phase detection step" is done by inputting the servo on signal just after the controller power is turned on. The “motor phase detection step” operates the table/rod to the maximum distance of the lead screw. (The motor rotates in the reverse direction if the table hits an obstacle such as the end stop damper.) Take the “motor phase detection step” into consideration for the installation and operation of this actuator 2 General Instructions (continued) Caution • Keep the controller and product combined as delivered for use. The product is set in parameters for shipment. If it is combined with a different product parameter, failure can result. • Check the product for the following points before operation. • Damage to electric driving line and signal lines. • Looseness of the connector to each power line and signal line. • Looseness of the actuator/cylinder and controller/driver mounting. • Abnormal operation. • Stop function • When more than one person is performing work, decide on the procedures, signals, measures and resolution for abnormal conditions before beginning the work. • Also designate a person to supervise the work, other than those performing the work. • An operation test should be performed at low speed, start the test at a predefined speed, after confirming there are no problems. • Actual speed of the product will be changed by the workload. Before selecting a product, check the catalogue for the instructions regarding selection and specifications. • Do not apply a load, impact or resistance in addition to a transferred load during return to origin. In the case of the return to origin by pushing force, additional force will cause displacement of the origin position since it is based on detected motor torque. • Do not remove the nameplate. 2.5 Actuator with lock Warning • Do not use the lock as a safety lock or a control that requires a locking force. The lock used for the product with a lock is designed to prevent dropping of work piece. • For vertical mounting, use the product with a lock. If the product is not equipped with a lock, the product will move and drop the work piece when the power is removed. • "Measures against drops” means preventing a work piece from dropping due to its weight when the product operation is stopped and the power supply is turned off. • Do not apply an impact load or strong vibration while the lock is activated. If an external impact load or strong vibration is applied to the product, the lock will lose its holding force and damage to the sliding part of the lock or reduced lifetime can result. The same situation will happen when the lock slips due to a force higher than its holding force, as this will accelerate the wear to the lock. • Do not apply liquid, oil or grease to the lock or its surroundings. When liquid, oil or grease is applied to the sliding part of the lock, its holding force will be reduced significantly. • Take “measures against drops” and check that safety is assured before mounting, adjustment and inspection of the product. If the lock is released with the product mounted vertically, a work piece can drop due to its weight. 2.6 Please refer to the auto switch references in “Best Pneumatics “ when an auto switch is to be used. 2.7 Unpacking Caution • Check the received product is as ordered. If a different product is installed from the one ordered, injury or damage could result.

LECP6-TFM107 Draft 8 CE Directive 8 CE Directive (continued) The LE series of actuators, motor controllers and teaching box conform to the EU EMC directive, if they are installed in accordance with the following instructions. These components are intended for incorporation into machinery and assemblies forming part of a larger system. The CE compliance was achieved when the above three components were connected as shown in the diagram below. • P-Clip or U-Clip installation The function of the P-clip or U-clip is to provide a 360° metallic contact and is a convenient method of ensuring an effective RF ground. When dealing with EMI issues it is important to know that the DC connection does not maintain the integrity of an AC high frequency connection. High frequency bonding typically involves using wide flat cabling to establish an effective system ground. When applied correctly the P-clip or the U-clip will provide a high frequency connection. When installing a P-clip or U-clip (see figure below) install the clips as close to the cable ends as possible. In order to provide a suitable ground connection surface, it may be necessary to remove the paint from the panel or the cabinet, an earth stud or a bus bar are also acceptable. Remove only the outer vinyl jacket of the braided screened cable (this allows the cable braid to connect to the P-clip or U clip). Take care not to damage the braiding. Snap the P-Clip or the U-Clip over the exposed braiding and adjust for a tight fit. Secure the clip to the designated ground with a machine screw and lock washer. The use of a brass or other conductive insert is recommended. Soldering a pigtail to the cable shield is not a suitable method for providing good RF ground. Please note that the EMC changes according to the configuration of the customers control panel and the relationship with other electrical equipment and wiring. Therefore conformity to the EMC directive cannot be certified for SMC components incorporated into the customer’s equipment under actual operating conditions. As a result it is necessary for the customer to verify conformity to the EMC directive for the machinery and equipment as a whole.
