Note

：

L2 is 2 to 3mm longer than L1

Step 2

Insert the exposed core wires into the OT terminal and crimp them

by using a crimping tool, as shown in Figure 4-2.

Figure4-2 Preparing a ground cable (2)

Note 1:

L3 is the length between the insulation layer of the ground cable and the

crimped part.L4 is the distance between the crimped part and core wires protruding from
the crimped part.

Note 2:

The cavity formed after crimping the conductor crimp strip shall wrap the

core wires completely. The core wires shall contact the terminal closely.

Step 3

Install the crimped OT terminal, flat washer using M6 screw, and

tighten the screw to a torque of 6 N.m using an Allen wrench.
