• 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.
Wiring Procedure
• Connect the power supply lines to the L and N power supply
terminals.
(the power suplly neutral to the N terminal.)
• Connect an earth ground line to the screw.
