Procedure for modular connector connection
1) Strip the outer sheath of a LAN cable end. Be sure not to scratch or peel off any wire insulation when stripping the sheath.
Figure 17. Stripping the sheath
Make sure there are eight wires inside the sheath.
2) Align the eight wires in the order specified by the LAN cable manufacturer.
An alignment example of the LAN cable wires is shown in the table below.
Figure 18. Alignment of the wires
Note:
* The color alignment shown above may not agree with your LAN cable specification. Ask your LAN cable manufacturer for the latest
specification.
3) Insert the aligned wires into a modular plug.
Figure 19. LAN cable insertion into a modular plug
Pin assignment of the modular plug in Fig. 19 is the image when the contacts and the cable stopper of the modular plug are
viewed from above.
Before inserting the wires into the modular plug, even out the length using a nipper. Note that the modular plug may not be
crimped on wires if the wire insulation is stripped too long.
4) Crimp the modular plug using a crimper. Insert the wires into the modular plug so that the contacts of the modular plug stick
into the wires after crimping. Crimped modular plug is secured on the LAN cable by the cable stopper of the modular plug.
Check the contacts and the cable stopper when crimping the modular plug.
5) Follow 1) to 4) for the other end of the LAN cable.
6) Check continuity of the LAN cable. Modular cable tester (Part No. DY7206A0000) facilitates the continuity check. At the
same time, make sure that the wires are aligned in the specified order, the modular plug contacts stick into the wires, and
that there is no cable damage or disconnection.
7) Connect the modular plugs to the modular jacks.
After successfully finishing the continuity check, insert a modular plug of the LAN cable into the modular jack of Infilex VC
and the other modular plug into the modular jack of the user terminal / temperature sensor / sub remote unit (also known as
"sub controllers") connected via LS-bus.
Insert a modular plug until it clicks and gently pull the cable to check complete connection.
