(3) Connecting the input signal cable:
Strip the sheath from the end of each conductor of a 2-core individually shielded cable as shown in Figure
LF622
5.9. Twist those shields and cover them with a thermal contraction tube or vinyl tube not to make contact
with the case or core wires. Then attach an M3.5 crimping terminal with insulated sleeve as shown in
Figure 5.8. Connect a crimping terminal to the A and B terminals on the terminal block and connect to
each G terminal of the detector and converter.
● Notes on signal cable shield processing work
When stripping an external sheath, intermediate and insulated sheath, be careful not to scratch or cut the
internal conductors and shield mesh. Do not disjoint the shield mesh but treat it as shown in Figure 5.9.

a. Open the shield mesh with a pair of tweezers or the like.
b. Pull out the internal coated wires from the hole of the
shielded mesh.
c. Pull out all internal coated wires and extend the shield mesh
