Doing so may resoult in malfunction. !WARNING Fig. 2 Enabling switch section Always verify the operation of the safety functions before starting the system. Not doing so may result in the safety functions not performing as expected if the wiring or settings are incorrect or the switches have failed. Do not drop the switch. Doing so may damage the switch and the system may continue to operate, possibly causing injury or death. Mounting bracket A4EG-OP2 (sold separately) Precautions for Safe Use • This product is a switch for teaching the machine such as robot in hazardous area. The machine is allowed to operate only when operating the switch continuously. Configure the system so that the machine can be operated only at position 2. • Apply load current not to exceed the rated value. • Do not use the switch submerged in oil or water or in locations continuously subject to splashes of oil or water. Doing so may result in oil or water entering the switch. • Do not use the switch in locations where explosive or flammable gasses may be present. • Mount the switch securely to prevent it from falling. Otherwise, injuries may occur. • The durability of the switch is greatly influenced by the switching conditions. Always test the switch under actual conditions before application and use it in a switching circuit for which there are no problems with performance. • Always attach the cover after completing wiring and before using the switch. Electric shock may occur if the switch is used without the cover attached. • The user must not maintain or repair equipment incorporating the switch. Contact the manufacturer of the equipment for any maintenance or repairs required. • Do not disassemble or remodel the switch in any case, or the switch will not operate normally. • Do not override by inserting the Holding Key itself in the door switch. • Configure the circuit so that the machine does not operate when operating the Enabling Switch while the Holding Key is being inserted in the door switch. • Do not impose excessive vibration or shock on the Door Switch while the Holding Key is inserted. Excessive vibration or shock may cause the Switch to fail or break. • Do not incline and pull the switch body or do not impose shock on the switch body in the directions shown with the arrows in Fig.1. Otherwise, the switch may be damaged and may not operate properly. • Refer to the D4NS Safety-door Switch Datasheet and Instruction Sheet about the storage, ambient conditions, the details and handling of the Switch. Fig. 1 Insertion-pull direction (Perpendicular direction) A4EG Top position No operation No operation No operation Holding Key A4EG-OP3 (sold separately) D4NS (sold separately) No operation Arrow indicates insertion-pull direction. Precautions for Correct Use • Do not hold the Enabling Switch Device at Position 2 by any other methods except for handling. Otherwise, the original function of the Enabling Switch Device is not worked. Operating Environment • This switch is designed for use indoors. Using the switch outdoors may damage it. • The switch contacts can be used with either standard loads or microloads. Once the contact be used to switch smaller loads. The contact surfaces will become rough once they have been used and contact reliability for smaller loads may be reduced. • Do not use the switch in the following locations. • Locations where the interior of the Protective Door may into direct contact with cutting chips, metal filings, oil chemicals • Locations subject to detergents, thinners, or other solvents • Locations subject to sudden temperature changes • Locations subject to high humidity and condensation • Locations subject to severe vibration • Do not use the switch where corrosive gasses (e.g., H2S, SO2, NH3, HNO3, or Cl2) are present or in locations subject to high temperature and humidity. Doing so may result in damage to the switch as a result of contact failure or corrosion. • Do not store the switch where corrosive gasses (e.g., H2S, SO2, NH3, HNO3, or Cl2) or dust are present or in high temperature and humidity. • If the switch is not turned ON and OFF for a long period of time, contact resistance may be increased or continuity failure may occur due to contact oxidation. Mounting Method Specified Tightening Torque Loose screws may result in malfunction. Tighten the screws at the specified torques. Item Cover mounting screw Terminal screw Holding Key mounting screw Conduit Connector mounting (Conforming spanner 27 mm (width across flats)) Mounting Bracket Specified torque 1.1 to 1.3 N·m 0.4 to 0.5 N·m 0.5 to 0.7 N·m 2.0 to 2.4 N·m 2.4 to 2.8 N·m Cover Mounting • Dislocation of the seal rubber or foreign substance on the seal rubber reduces seal performance of the switch. Mount the cover after confirming that there is no abnormality on the seal rubber. If the seal rubber cracks or breaks, replace the Cover with a new one (A4EG-OP1 Rubber Cover, separately sold). • Do not touch the rubber boot with sharp objects. Otherwise, the rubber boot may break and the operating characteristics and the seal performance may not be satisfied. Seal Cover, A4EG-OP1 (sold separately) Magnified View Mounting surface Rubber boot Seal rubber 11 A4EG Installing Mounting Bracket • Securely install the Mounting Bracket using M5 screws and washers and tighten them to a torque of 2.4 to 2.8 N·m. • Do not pull the cable when the Enabling Switch Device is hung on the Bracket. Holding Key Type (sold separately) • Use the A4EG-OP3 Holding Key when using the A4EG combining with the door switch. • Use the D4NS Safety-door Switch. • Loose screws may result in malfunction. Tighten the screws at the specified torques. Adhesive is recommended to prevent screws from being loose. The specified torque: 0.5 to 0.7 N·m (Mounting screw, 2pcs.) • Do not impose excessive force on the tip of the Holding Key or do not drop the switch body when the Holding Key is mounted on the switch body. Otherwise the Holding Key may deform or break. Stop using in case that deformation or breakage of the Holding Key occurs. • Use the provide Spring washers and Mounting screws when mounting the Holding Key. Fit a tip of a slotted-screw driver on the head of the Mounting screw as shown in the following figure when tightening Mounting screws. The Mounting screws cannot be released once tightened. A4EG Bracket A4EG-OP2 (sold separately) • Use crimp terminals with insulator tube for wiring. Recommended crimp terminal (Ring tongue terminal, Nyloninsulated): J.S.T. Mfg Co.

Lead Wire Lengths Spring washer, 2 pcs. (provided) Mounting screw, 2 pcs. (provided) • As shown in figure 1 in Precautions for Safe Use, install the D4NS so that its mounting surface is above the highest part of the A4EG. • As shown in figure 1 in the Precautions for Safe Use, use the Holding Key inserted vertically to the insert hole. Using the A4EG-BE2R041 (Enabling Grip Switch Equipped with an Emergency Stop Button) If the A4EG is installed in a machine, do not use the A4EG alone as an emergency stop switch or as an emergency shutoff switch as specified by SEMI-S2. SEMI-S2 specifies the installation of emergency shutoff switches at specified intervals on equipment. The A4EG can be removed from the equipment, and so may not satisfy the requirements of SEMI. Use the A4EG in combination with emergency stop switches or emergency shutoff switches that are installed at fixed positions. Wiring • Confirm that safety is satisfied on the operation of the equipment to wire. • Do not put the electric power when wiring. Otherwise electric shock may occur. • Use an adequate diameter of cable. The seal performance is reduced when the diameter is smaller than the adequate diameter. • Use the conforming sizes of lead wires to the apply voltage and current. Conforming cable size Recommended multi-wire cable size: AWG20 to 18 (0.5 to 0.75 mm2) Recommended cable diameter: 8.0 to 13 mm (used with provided Conduit Connector) • Do not pull the lead wires with excessive force. Doing so may disconnect them.
