Installing the Switch Attach rubber packing or the Yellow Plate onto the Switch from its terminal side. Insert the Switch 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 to the protruding part of the unit. Rubber packing is not necessary when the Yellow Plate is used. Tighten the nut to the torque of 0.49 to 0.78 N S m (5 to 8 kgf S cm). Case should be installed with its protruding part adjusted to the slit of the panel hole. Align the lock ring to the groove of the case so that the edge is drawn to the panel side. Lock Panel Mounting nut Cutout Rubber packing (attached to the product) or yellow plate (sold separately) Lock hole Panel Lock ring Rubber packing or yellow plate (sold separately) 2. Mounting the Socket Unit Snap on the Socket Unit to the Switch. Make sure the Switch and the Socket Unit are in the proper orientation. Align the thin indentations on the case with the white pushbutton markings on the Socket Unit and press the parts together. 3. Removing the Switch Grip the part between the Switch holder of the case and the Switch Unit using the A16Z-5090 Extractor, and pull to remove the Switch Unit. Extractor (A16Z-5080) 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 case. Protruding part 6 A165E A165E Precautions Correct Use Mounting Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Otherwise electric shock or fire may result. Tighten the mounting nut to the torque of 0.29 to 0.49 N S m (3 to 5 kgf S cm). Wiring Select an appropriate cable size depending on applied voltage and current. Solder properly according to the following conditions. Improper soldering may generate abnormal heat and cause a fire. Wait for one minute after soldering before exerting any external force on the solder. 1. Manual Soldering: 30 W, within 5 s 2. Automatic Soldering: 240°C, within 3 s Use non-corrosive rosin liquid as 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 insulation distance. Operating Environment The structure with the IP65 enclosure rating will not be affected by direct water splashing onto the front side of the panel at any angle. LED No external resistors are required because the Switch has a built-in LED current-limiting resistor. Rated voltage 24 VDC Built-in limiting resistor 1,600 Ω Operating Torque Operating torque of the Selector Switch and Emergency Stop Switch should be no more than 0.49 N S m (5 kgf S cm). Others The oil-resistant IP65 uses NBR rubber and is resistant to general cutting oil and cooling oil. Some particular oils cannot be used with the oil-resistant IP65, however, so contact your OMRON representative for details. If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after coating. 7
