SCAN-LAN VI
1. Insert
each wire
into its terminal and tighten screw until snug (see
Figure D-3). If you’re using ScTP, connect the drain wire to the center
screw terminal of the center terminal strip.
2. Check to see that there are no stray wire strands outside terminal
clamps and make sure all wires are properly tightened into their
terminals.
3. Make sure that each pair twist is correct, and that the four wire pairs
exit radially from the cable jacket as before. Rotate the entire cable so
the fan of wires is flat and parallel to the circuit board.
4. Slide the grommet until
1
⁄
32
inch (0.8 mm) or less of cable jacket is
exposed (see Figure 1-1). Rotate the grommet so that its flats are
parallel with the circuit board when the fanned wires are flat to the
circuit board.
Install new tie wrap centered on grommet sleeve as shown in Figure
D-3. When the tie wrap is finally tightened, its ratchet box should be
approximately in the plane of the wire fan.
5. Tighten tie wrap as much as possible (until wrap material begins to
stretch). Cut off excess tie wrap.
6. Carefully guide the grommet and circuit board into the case. Once the
cylindrical neck on the grommet is through the hole, use the neck to
pull the grommet into place. The twisted pairs will bunch up when
properly installed. If necessary change their positions to avoid
pinching.
NOTE
If using ScTP, the drain wire must not short against the circuit shield
nor the case (if case is copper painted). Shorten the drain wire by
cutting as required to accomplish clearance.
7. Reinstall the 4-40 screws from the open side of the case. Make sure the
screws extend through the circuit board and into the plastic of the
case.
8. Reinstall the Performance Module in the SCAN-LAN VI body by
alternately turning each knurled thumbscrew a small amount or
turning them simultaneously. Only tighten these screws finger-tight.
