Open the port side cover of the scanner unit to access terminal boards.
Fabricating signal cable S03-80
1. Shorten the cable, extending the length actually required by 800 mm. Strip off
about 600 mm of the anti-corrosive vinyl sheath, and 790 mm of the armor
and the inner vinyl sheath, being careful not to nick the braided shield.

2. Unravel the outer shield with a screwdriver or similar tool to expose the cores
beneath the outer shield.

for future identification.

5. Ground the armor through the two washers as shown above. Trim the shields
considering their location on the earth terminal inside the scanner unit. Fit a
crimp-on lug (yellow, FV5.5-4, ø4) to inner and outer shields, then connect
them to the ground terminal inside the scanner unit.
