Configuring a Network
Warning
Turn off the power to the inverter before installation and network connection. Installing or removing the
communication module while the power is on may damage the inverter and the LonWorks communication module.
Make sure that the inverter is fully discharged before installing or removing the H100 LonWorks communication
Module.
The LonWorks network allows for various types of network topology.
Appropriate network termination is required to guarantee data reliability and to reduce noise. The H100 LonWorks
communication module has built-in terminal resistance. Therefore, network termination can be made by simply
turning on the termination switch.
For a bus network, turn on the termination switch of the H100 LonWorks communication modules at both ends.
