The LonWorks interface features Echelon’s Smart free topology transceiver (FT3150). The FT3150 transceiver is also directly compatible with
Echelon’s LPT-10 Link Power transceiver. A single twisted pair cable can be shared by these transceiver types. The primary network connection
is 3-way pluggable Phoenix-style connector included with the option card. The center position is for the shield while the outer positions are for
the twisted pair cable, as shown below. The network connection is polarity insensitive.

Terminal S1 Safety Interlock Control
A normally closed safety interlock must be connected to the drive’s terminals S1 and SN. When the connection between S1 and SN is broken,
the drive will automatically stop. The drive Run will restart once the connection is re-established. Refer to the appropriate drive user,
programming and/or technical manual for the proper use and wiring of a safety interlock circuit. If a safety interlock is not used, a jumper must
be present between terminals S1 and SN.
For E7B and E7L units refer to the schematic and instructions that came with the unit, along with the appropriate technical manual for
connection and use of the safety interlock.
