2-2 Installing the Adapter
3. Open the drive cover.
4. Connect a cable to the network, and route it through the bottom of
the PowerFlex drive. (Refer to the LonMark Layers 1-6
Interoperability Guidelines, Appendix A “Cable Requirements for
the TP/FT-10 Channel.”)
5. Connect a six-pin linear plug to the network cable. (See Figure 2.1
for the terminal definitions.)
Figure 2.1 Bus Topology with Shield Example
6. Insert the six-pin linear plug into the mating adapter socket.
Terminal Name Function
1 SHIELD
(1)
(1)
It is recommended to use shielded network cable. This shield must be grounded at one point
on the network via a 470K ohm, 1/4 watt, ≤ 10% metal film resistor.
Noise mitigation
(2)
(2)
For noise mitigation, LON trunk lines should not be run in close proximity to drive or
equipment power distribution feeds.

(3)
topology networks.
(3)
To terminate a Bus Topology network (one termination at each end of the network), connect
TERM COM to TERM BUS.
