Fabricating signal cable S03-81
1. Remove the vinyl sheath by 450 mm.
2. Slide the clamping ring, washer, rubber
gasket and washer onto the signal cable
in that order.
3. Unravel the outer shield to expose the
cores in the outer layer. Then, unravel the
inner shield to expose the cores in the in-
ner layer. Label all inner cores to aid in
identification.
4. Attach EMI cores to all inner cores and all
outer cores, and tie them with cable ties,
etc..
Note: There are two types of the EMI core,
thick and thin.
5. Trim each core (except coaxial wire) con-
sidering its location on the terminal board.
6. Trim the inner and outer shields leaving
500 mm each. Twist shields together and
attach crimp-on lug FV5.5-4 (blue, ø4).
7. Remove insulation of each core by about
6 mm. Fix crimp-on lug FV1.25-M3 (red,
ø3) to each core.
8. Fabricate the coaxial cable. Make the
length 10 mm longer than the shield to pre-
vent wire strain. Attach crimp-on lug
FVD1.25-3 (red, ø3) to coaxial cable.
