CHARACTERISTICSApplication tools & process (coupled with backshell HE 308-35-25-30-36)For this power connector, we recommend the use of our backshell HE 308-35 for optimum performance.Tool references• For size 16 contacts:• Crimping pliers• Turret positioner(Position number 5)• Removal tool• For size 4 contacts• Crimping pliers& a pair of jaws (One of the jaws isequipped with a positioning stop )• Removal tool (4 are needed)• For the rear accessories: 2 possibilities➊ ITS System• Pliers• Tool• Tool❷ BAND-IT System• Tool809857809858809944809947809948809943809949809950809951809952Installation instruction• Cable preparation• We recommend the use of the band backshell with aminimum chamber diameter of 30mm suitable for thesize of conductors.• First place the heat-shrink sleeve over the cablefollowed by the backshell HE308-35.• Stripping process• Cut the jacket from the cable taking care not todamage the braid.• Comb the braid back and stick it to the outer jacketwith adhesive.• Trim the size 4 conductors to 65mm ensuring there isno difference in the lengths of these conductorsgreater than 1mm. (This is to avoid damage to clips inthe insulator) (See figure 1).• Crimping process• Crimping of size 16 contacts (Locator positioned number 5)- The strip length of the size 16 conductors should be 6mm.- Crimp the contact of each size16 wire with the corresponding tool.- After having crimped the size 16 contacts fold them back and position them with adhesive (see figure 2).• Crimping of size 4 contacts- The strip length of the size 4 conductors should be 13 mm.- Choose male or female positioning stop on your corresponding crimping tool.- Crimp the contacts.• Contact insertion• Check the position of each contact before inserting it in the cavity.• Insert firstly the 4 size 4 contacts in the insulator and push them until locked, and secondly do the same forsize 16 contacts.• Removal process• Take off the heat shrink sleeve and remove the band, fold back the braid and screw off the backshell.• Remove the size 16 contacts one by one using the tool 809944.• Fold back size 16 wires and secure them with adhesive.• Then remove secondly the 4 size 4 contacts at the same time, using 4 removal tools (see figure 3).Figure 180 ±0,515 ±0,5 Figure 2adhesive≈ 1 mmbraidadhesivesize 4 conductorsize 16 conductorsize 4 conductorFigure 34 removal tools30 minstraight
