(SHA-LN16UG(B))
x
This interface contains 4 LonWorks communication boards
(nodes).
x
Up to 4 indoor unit groups (maximum 32 units) can be assigned
to 1 node.
LonWorks Interface Structure
When AC 200-240V power is connected, connect the power
transformer primary-side to CN006. When AC 100-120V power is
connected, connect the power transformer primary-side to CN005.
(It is connected to CN006 when the unit is shipped from the plant.)

The LonWorks communication lines can be connected to either
(1) or (2) in the above figure. The results are the same.
x
Do not run the indoor/outdoor control lines, the LonWorks
communication lines, and the power cables through the same
conduit, or place the cables near one another. Doing so can cause
the system to malfunction.
