Figure 29. TX and RX SUMA
The bend radius for the lead-in cable is 9 cm (3.5 in). This should be adhered to for the coils of
spare cable at the SUMAs and inside the processor enclosure. The coils of spare cable at the
SUMA need ferrite bead clamps applied, as shown in, Figure 30.
Note: TX and RX coils are next to their respective SUMA, not on top of each other.
Figure 30. Ferrite Bead Clamp
The TX (protected side) SUMA will have a TX 1 connection to one SUM and TX 2 to the other
SUM. The same applies to the RX SUMA, respectively.
