(OT cable terminal crimping area)
2) Strip the insulation of the wire past the cable crimping area of the OT terminal,
then use a hydraulic crimp tool to crimp the terminal. The crimped portion of the terminal
must be insulated with heat shrinkable tube or insulating tape.
NOTE:
If chosing aluminum alloy cable, you must use copper aluminum transfer
terminal in order to avoid direct contact between copper bar and Aluminum
