(1) Installing the Operation Unit • Attach rubber packing or the Yellow Plate onto the Operation Unit from its terminal side. Insert the Operation Unit into the panel from the front. Install the lock ring and mounting nut from the terminal side and tighten. • Adjust the slits on the hole of rubber packing and Yellow Plate Lock to the protruding part of the Unit. • Rubber packing is not necessary when the Yellow Plate is used. Cutout • Tighten the nut to the torque of 0.29 to 0.49 N·m. • The Operation Unit should be installed with its protruding part adjusted to the slit of the panel hole. • Align the lock ring to the groove of Lock hole the Operation Unit so that the edge is drawn to the panel side. Panel Mounting nut Rubber packing (included with the product) or Yellow Plate (sold separately) Edge Panel Lock ring (included with the product) Mounting nut (included with the product) (2) Mounting the Switch Lock ring (included with the product) Rubber packing (included with the product) or Yellow Plate (sold separately) (3) Removing the Switch • Snap on the Switch to the Operation Unit. • Make sure that the Switch has the correct orientation when snapping it onto the Operation Unit. • Align the white dot on the Operation Unit with the guide groove on the side of the Switch marked with an “L” as shown below, and push the Switch into the Operation Unit until it clicks into place. Confirm that the Switch is securely in place before using. • Insert the prongs of the A16Z-5080 Extractor between the Switch and the Operation Unit, grip the Switch, and pull to remove. Guide groove White dot Extractor (A16Z-5080) L marking (4) Installing the LED Lamp • When mounting the Lamp, make sure it is facing the direction shown in the following diagram. Insert the Lamp while matching the protruding part of the Lamp and the small guides on the outer surface of the switch. Narrow guide Protruding part Wide guide 8 A165E Safety Precautions Be sure to read the precautions for all pushbutton switches in the Pushbutton Switches Group Catalog (Cat. No. X032). !CAUTION If the Operation Unit is separated from the Switch Unit, the equipment will not stop, creating a hazardous condition. Always confirm that safety functions are operating before starting operation. LEDs The LED current-limiting resistor is built-in, so external resistance is not required. Rated voltage Precautions for Correct Use 24 VAC/VDC Internal limiting resistor 2.4 kΩ Operating Torque Mounting • Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Electrical shock or fire may result if the power is not turned OFF. • The tightening torque is 0.29 to 0.49 N·m. Wiring • Be sure to use electrical wires that are a size appropriate for the applied voltage and carry current. Perform soldering according to the conditions given below. If the soldering is not properly performed, abnormal heating may result, possibly resulting in fire. 1. Hand soldering: 30 W, within 5 s 2. Dip soldering: 240°C, within 3 s Wait for one minute after soldering before exerting any external force on the solder. • Use non-corrosive resin fluid as the flux. • Make sure that the electric cord is wired so that it does not touch the Unit. If the electric cord will touch the Unit, then electric wires with a heat resistance of 100°C min. must be used. • After wiring the Switch, maintain an appropriate clearance and creepage distance. • Do not exceed an operating torque of 0.49 N·m in the direction of rotation. • Do not pull the operating button or apply excessive force to any side of the button. Otherwise it may be damaged. Others • The oil-resistant IP65 uses NBR rubber and is resistant to general cutting oil and cooling oil. Some special oils cannot be used with the oil-resistant IP65, however, so contact your OMRON representative for details. • If the panel is to be coated, make sure that the panel meets the specified dimensions after coating. • Due to the structure of the Switch, severe shock or vibration may cause malfunctions or damage to the Switch. Also, most Switches are made from resin and will be damaged if they come into contact with sharp objects. Particularly scratches on the Operation Unit may create visual and operational obtrusions. Handle the Switches with care, and do not throw or drop them. Operating Environment • The IP65 model is designed with a degree of protection so that it will not sustain damage if it is subjected to water from any direction to the front of the panel. • The Switch is intended for indoor use only. Using the Switch outdoor may cause it to fail. Do not allow the Switch to drop and hit the floor. Using the Microload Voltage (V) • Insert a contact protection circuit, if necessary, to prevent the reduction of life expectancy due to extreme wear on the contacts caused by loads where inrush current occurs when the contact is opened and closed. • The A165E-@U (one-piece construction) allows both a standard load (125 V at 1 A, 250 V at 0.5 A) and a microload. If a standard load is applied, however, the microload area cannot be used. If the microload area is used with a standard load, the contact surface will become rough, and the opening and closing of the contact for a microload may become unreliable. • The minimum applicable load is the N-level reference value. This value indicates the malfunction reference level for the reliability level of 60% (λ 60) (conforming to JIS C5003). • The equation, λ 60 = 0.5 x 10−6/time indicates that the estimated malfunction rate is less than 1/2,000,000 with a reliability level of 60%. Do not place or drop heavy objects on the Switch. Do not operate the Switch with hard or sharp objects.
