(2) Installing/Replacing on the Switch • Grip the indicator with your fingers, then rotate the indicator while pressing it against the Switch. Control Box (Enclosure) (1) Mounting the Switch (2) Creating a Cable Port Hole The Standard-size Legend Plate Frame can be mounted. Mount the Frame as shown in the following diagram. Mount the Switch in the same way as for an ordinary panel. Place the tip of a screwdriver on the surface where the cable port hole is to be created with the cover attached and strike the screwdriver to punch a hole. Attempts to punch a hole on the other side of the case will damage the Box. (3) Securing the Connector Cable 1. Insert the connector into the cable port hole in the Box and secure with the Mounting Ring inside the box. 2. Pass the tightening cap through the cable, insert the cable into the connector, and tighten the tightening cap to secure the cable.

Safety Precautions Be sure to read the precautions for All PushButton Switches in the website at:http://www.ia.omron.com/. Indication and Meaning for Safe Use CAUTION Precautions for Safe Use Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury or in property damage. Supplementary comments on what to do or avoid doing, to use the product safely. !CAUTION Do not apply a voltage exceeding the rated voltage across the incandescent lamp terminals. The lamp may be destroyed and the operation unit may fly out. If the Operation Unit is separated from the Socket Unit, the equipment will not stop, creating a hazardous condition. Secure the lever on the Socket Unit by using the A22Z-3380 Lock Plate so that the Operation Unit cannot be easily separated from the Socket Unit. (Refer to “Mounting the Lock Plate” at the right.) Precautions for Correct Use Mounting • Always make sure that the power is turned OFF before wiring the Switch. Also, do not touch the terminals or other current-carrying ports while power is being supplied. Electric shock may occur. • Do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting ring. The tightening torque is 0.98 to 1.96 N·m. • Recommended panel thickness: 1 to 5 mm. • When mounting the caps after changing the LED or the caps, tighten the caps at a tightening torque of 0.49 tp 0.78 N·m. Mounting the Lock Plate 1. Confirm that the lever on the Mounting Latch is on the side where the Operation Unit is secured and then insert the protrusion on the Lock Plate into the hole in the lever on the Mounting Latch. 2. Press the hole on the Lock Plate onto the protrusion on the Mounting Latch until it clicks into place. Lever Lock Plate 2 1 Operation Unit Mounting Latch 17 A22E Using the Microload • Terminal screws must be Phillips or slotted M3.5 screws with a square washer. • The tightening torque is 1.08 to 1.27 N·m. • Single wires, stranded wires, and crimp terminals can be connected to the Switch. • Applicable Wiring Materials: Twisted strands: 2 mm2 max. Solid wire: 1.6 mm dia. max. Naked Crimp Terminals 8 mm max. 16.0 mm max. Crimp Terminals with Insulating Sheaths 16.0 mm max. 8 mm max. 20.2 mm max. 8 mm dia. max. Contact failure may occur if a Switch designed for a standard load is used to switch a microload. Use Switches within the application ranges shown in the following graph. Even within the application range, 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 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%. Voltage (V) Wiring 8 mm dia. max. 0.16 mA 100 mA 1.6 mA 30 24 20.2 mm max. Microload area • After wiring the Switch, maintain an appropriate clearance and creepage distance. 12 Invalid area Operating Environment • The IP65 model is designed with a protective structure 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. LEDs • The LED current-limiting resistor is built-in, so internal resistance is not required. • If commercially available LEDs are used, select the ones that meet the following conditions: Base: BA9S/13 Overall length: 26 mm max. Power consumption: 2.6 W max. When DC-specific LEDs are used, wire the Switch so that the X1 terminal is positive. • Mis-lighting of the LED The LED lights with approx. 0.1 mA or less of micro-current. Take a countermeasure like adding a resistor to prevent mis-lighting in parallel to the LED. The micro-current varies with the machine (leak current or stray capacity between cables, etc.). Select resistance value and allowable power consumption that meet the actual current. Area of use Standard load area 5 0 0.1 1 mA 10 mA 1 10 100 1,000 Current (mA) Others • 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. Do not allow the Switch to drop and hit the floor. (Circuit example) In case of using 24 VAC/VDC, Direct lighting X1 LED lamp R:10kΩ (1W) Bleeder resistor Do not place or drop heavy objects on the Switch. X2 Do not operate the Switch with hard or sharp objects. Hammer Screwdriver 18 Terms and Conditions Agreement Read and understand this catalog.
