To assemble the wire: first, strip the wire by 7-8mm according to the strip gauge. STEP1 for connecting the wire: use a flathead screwdriver to push in the operating lever until it locks. STEP 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. STEP 3: Insert the screwdriver into the release slot, and release the locking mechanism until a click is heard by resetting the lever. STEP 4: Make sure that the operating lever is reset. After assembling all contacts, pull the wires gently to make sure that there is resistance, which indicates that the connectors are wired correctly. To remove the wires, push in the operating lever, remove the wires, and reset the operating lever.
