Make sure that the following operations have been performed. • Check that the operating lever is reset. • Check that the procedure in step 2 has been followed. (Pull gently on the cable to make sure that there is resistance, indicating that the Connectors are wired correctly.) 7 to 8 mm Connecting the Cable to the Connector 1. Use a flat-blade screwdriver to push down the operating lever inside the operation slot until it locks. Flat-blade screwdriver Operation slot 2. Insert the wire fully to the back of the wire insertion hole. Make sure that the cable sheath is inserted into the hole, and that the end of the wire has passed through the contact section. Contact section Cable sheath Wire insertion hole Removing Cables from the Connector 1. Press down on the operating lever to lock the lever before removing the cable. 2. After removing the cable from the Connector, always reset the operating lever, except when rewiring the Connector. The Connector can be rewired without resetting the operating lever.

Doing so may cause damage to the Connectors or cause the cables to disconnect. • Install the Connectors in a location where they will not be stepped on, to prevent disconnection of the cables or damage to the Connectors. If the Connectors have to be installed in such a location, use a protective cover. • Make sure that the Connectors are mated in the correct direction. Mating the Connectors incorrectly will damage to the Connectors. • Do not use the Connectors if the lock lever is bent or broken. Doing so may cause the Connector to become loose or the device to malfunction. • Before mounting Connectors to a PCB, make sure that the Connectors are positioned in the correct direction. • Before bending a cable to connect it to a Connector, check the bending specifications of the cable to be used. • Do not exceed the rated current of the cable. Always check the rated current of each cable to be used. • Do not use pliers or other tools to remove the Connectors. • Hold the Connectors firmly by hand when handling them. Do not use excessive force to push the Connectors. Forcing the Connectors may result in injury. • These Connectors do not resist water. Do not use Connectors in places where water or oil may be sprayed onto the Connectors. Wiring • Insert one wire into each insertion hole. Inserting two or more wires into a single hole may cause unexpected problems. • Make sure that no power is being supplied to a Connector before wiring, inserting, or removing the Connector. Doing so may result in electric shock. • Follow the wiring diagrams for the device being used when wiring the cables. • Strip the cables according to the instructions in the applicable operation manual, making sure not to damage the wires. • Do not use a screwdriver with a tip larger than the specified width when wiring the Connectors. • Make sure short-circuits are not created, e.g., by protruding wires. Inserting and Removing Connectors • When connecting or disconnecting Connectors, always hold the case of the Connector. • When mating Connectors, insert the Connector fully into the back of the socket, and then make sure that the Connector will not become loose by lightly pulling it in the opposite direction. Recommended Screwdriver • Use a flat-blade screwdriver with a tip of 2 mm max. Do not use screwdrivers that gradually widen towards the base of the screwdriver. • Using other screwdrivers may cause damage to the adjacent poles.
