Figure 5.17 Strip AC cable
NOTE: L2 (insulation stripping length) is 2mm-3mm longer than L1 (OT cable terminal
crimping area)
B)
Strip the insulation of the wire core, insert into the cable crimping area of the OT terminal, then use a
hydraulic crimp tool to crimp it firmly. The wire must be covered with heat shrinkable tube or insulating tape.
When using the heat shrinkable tube sleeve the heat shrinkable tube over the wire before crimping the OT
terminal.
