Preparations

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.

3. Similar to step 2, expose the cores beneath the inner shield. Mark all cores

for future identification.

4. Slide the clamping gland, washers and gasket onto the cable. (Use lower side

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.
