1.3 Outline of product
SJ-LW is LonWorks communication board for SJ300/L300P series inverter.
SJ300/L300P series inverter can get to connect another devices via LonWorks when install SJ-LW.
SJ-LW is possible to connect for all models of SJ300/L300P series.
The SJ-LW option card communicates according to the LonWorks Protocol Standard ANSI/EIA 709.1-A-1999.
This means that it can communicate with all LonWorks nodes that comply with this standard, but it does not
necessarily mean that all services available in the LonWorks standard are supported. The “LonMark
Functional Profile: Variable Speed motor Drive” (doc no. 6010_11) is supported.
In a control system the option board will act as a node that can be read and written to, from any other
LonWorks node that has SNVT’s that corresponds to the one on SJ-LW.
(Note) RS485 communication function is disabled by installing SJ-LW to the inverter.

NOTE : NET A and NET B connection is not polarity sensitive.
3.2 Network cabling
For detailed information about recommended cables for a LonWorks network, please see the FTT-10A Free
Topology Transceiver User’s Guide (doc.id.078-0156-01F) available at http://www.echelon.com
Below are some recommended cables :
-Belden 85102, unshielded
-Belden 8471, unshielded
-Level IV 22AWG, unshielded
-JY (St) Y 2x2x0.8, shielded
-TIA568A Cat.5 24AWG
Note) To be able to communicate in a noisy environment, and to fulfil all EMC-requirements, it’s
important that a shielded cable is used, and that proper grounding is provided.
3.3 Wiring note
1.Installing the cable to Network connector must be done after checking the power supply off.
2.Wiring should not have bare cables exposed between connector contacts.
3.Network cables should be fixed without tension. Cables fixed under tension have potential of causing a
communication fault by to be removed a connector.
4.Ensure external emergency stop measures are taken to stop the inverter, in the event of a network fault.
(a) Remove the Power supply of the Inverter when the network master detects a communication fault.
(b) When the master detects a communication fault, turn on the intelligent input terminal which would be
allocated (FRS), (RS) and/or (EXT) function.
