3. Instruction of cable connection and extraction 3-1 Cable Strip 䐟Use applicable size cable䠄Fig2䠅. And strip the cable to 8±0.5mm. (Fig3) 䐠If there is twist, bend or feazing. Please correct them. After correcting, check strip length. If there is excessive deformation, do not use the cable. 䐡Check the cut surface of conductor and insulation are flat. AWG Area of conductor [mm2] AWG22 0.32 AWG20 0.52 AWG18 0.82 AWG16 1.3 AWG14 2.1 ※Insulation Diameter 3.8mm Max. Fig. 2 Applicable Cable Fig. 3 Strip Length 8±0.5

3-2 Instruction for cable connection (Fig.4) 䐟Set the hook of opener(2347681-1) to the opener hole. 䐠Set the hinge of opener(2347681-1) to the spring slot. 䐡Push the opener(2347681-1) until cable insertion hole opens to the required size. Do not push strongly, there is possibility of damage to opener (2347681-1) and Receptacle Assembly. *About 30N is enough for AWG14 cable. 䐢Insert the cable to cable insertion hole. (Fig.4) 1) Cable insulation Diameter < 2.4mm The cable should be inserted until aligning cable insulation and end of guiding taper straight line. 2) Cable insulation Diameter ≧ 2.4mm The cable should be inserted until cable insulation contact the guiding taper.

4. Header Assembly The Header Assembly is PCB mount Horizontal type. 4-1 Recommended PCB Through hole type PCB is recommended. Refer to Drawing for layout and thickness. 4-2 Mount Header Assembly to PCB Insert straight until the Header Assembly is fixed to PCB by retention leg. (Fig.7) Confirm that there is no float and not tilt. (Fig.8) Set to PCB Push straightly Completed Fig.7 Mount to PCB Fig.8 Bad example PCB Retention Leg Float and Tilt

4-3 Flow solder mounting This product is lead free correspondence. Please set to appropriate temperature profile. Refer to Product Specification: 108-140221. 4-4 Soldering by hand work This product is lead free correspondence. Please set to appropriate temperature. Refer to Product Specification: 108-140221 5. Mating Receptacle Assembly and Header Assembly (Fig.9) Insert Receptacle Assembly straightly to Header Assembly until click sound is heard. *Do not touch the lock lever when inserting. Insert straightly Completed Fig.9 Mating 6. Unmating Receptacle Assembly and Header Assembly (Fig.10) Unmate connector after lock lever is depressed completely. If unmating connector without lock lever is depressed completely, there is possibility to damage assemblies, cable and PCB. Push lock lever completely Pull straightly 7. Others Completed Fig.10 Unmating Lock lever Lock lever

7. Others 7-1 When using in a place with a lot of vibration, fix the position 100 mm from the Receptacle Assembly. (Fig.11) 7-2 Avoid mounting to which cable is pulled in excess. 7-3 Don’t use Opener for D3900 and 3950 (1981045-1). There is possibility of damage the Receptacle Assembly.
