Installation

System Wiring

System wiring involves two installations:
connecting the network interface to the control unit (CU)
connecting the CU to the stations
On the network interface side, the method of connection
depends on the type of network interface that is installed.
On the station side, the method of connection depends on the
number of stations; 24 stations and under uses direct
connection, while over 24 stations requires building a cross-
connect field.
The recommended options for building the wiring field on the
station side are Interconnect Wire, a complete wiring kit that uses
110 jack-panel blocks, a template, wiring troughs, D-rings, and
D8W cords; or SYSTIMAX, a complete wiring kit containing 110
termination blocks with modular jacks, a 110A field-termination
block, a template, wiring troughs, D-rings, and patch cords.
CAUTION:
To avoid coupling power supply noise onto system wiring,
allow at least 3 inches of clearance between the basic
carrier's power supply and any wiring or termination
hardware located left of the CU.
Note: While there are many ways to connect the network
interface to the CU and the CU to the stations, the methods
shown here are the recommended ones.
