Earth for power wiring
• The LonWorks communication lines can be connected
to either (1) or (2) in the above fi gure. The results are the
same.
• Do not run the inter-unit 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.
• Before turning the power on, follow the instruction in Power
Board Initial Settings.
• When using the spare inter-unit cotrol line, connect [1] and [3]
at CN002.
• When using the spare LON communication line, connect [1]
and [3] or [4] and [6] at CN003.
