Redundant Power
Start-up Module
Assembly
The TD100 processor connects to the sensor cables using factory-made lead-in cables. The
lead-in cables are 10 m (30 ft) long, with connectors and ferrite beads attached. For a Middle
processor, two TX lead-in cables and two RX lead-in cables with the TX and RX cables are
installed in separate PVC conduit. Power is provided to the processor from the Start-Up Module
Assembly (SUMA) over the lead-in cables. Power cables may run inside the TX/RX conduits or
inside their own isolated conduit(s).
Excess lead-in cable is buried in a loop next to the respective TX or RX SUMA after the end of
the conduit leading to them. Install clamp-on ferrite beads to the spare lead-in coils. Lead-in
cable should maintain a bend radius of 9 cm (3.5 in) or greater, take note of this inside the
TD100 enclosure and coils at the SUMA location.
The processor should be mounted in an outdoor metal enclosure or inside a site facility on the
protected side of the perimeter. The TD100 enclosure can mount to a fence post or strut
structure. The cables connecting to the processor enter through the bottom of the enclosure via
conduit, as shown in Figure
m (1.6 ft) from the nearest cable. The conduit protects the cables from accidental cutting or
crushing.
