Installation Instructions

NOTICE
l When you strip a power cable, do not damage the conductor of the cable.
l If the bare crimping terminal is not provided by Huawei, the value of L1 is 1 mm to 2 mm
greater than the value of L.
l Add OT terminals to the power cable immediately after stripping a length of insulation jacket
off a power cable. Otherwise, the bare wires may distract from the center of the cable, which
affects the installation of OT terminals.
l If the bare wires distract and OT terminals cannot be installed, cut off the bare wires, strip
another length of insulation jacket off the cable, and add OT terminals to the cable.

NOTE
If you are proficient in assembling OT terminals and power cables, you can obtain the value of L1 by
comparing the part to be crimped with the power cable.
Step 2 Put the heat-shrinkable (A) tube onto the bare crimping terminal, as shown in Figure 16-4.
