Wiring the LonWorks Network (Release 9.0 only)

1.  Connect the 2-wire cable from the LonWorks network trunk to the removable 3-terminal

blue plug labeled LON as shown below. The LonWorks network trunk is available on the MS-

NAE3520-2 and MS-NAE4520-3 models at Release 9.0 only.

Figure  11: LonWorks network terminal block and wiring connections

2.  To add additional vendor devices, wire from one device to the next in a daisy-chained fashion.

Do not connect more than two wires to each terminal.
