Earth for power wiring
• The LonWorks communication lines can be connected to either
(1) or (2) in the above figure. 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.
