Tip: Connecting the RS485 of the ACP
64 outdoor units at maximum can be connected to one port of the RS485 of the ACP and 256
indoor units at maximum can be connected to one ACP. When there are many outdoor units to
connect, connect the outdoor units suitably from LG-NET1 to LG-NET4 with the BUS form.
Otherwise, the ACP may cause the malfunction.
The following figure shows the example for separately connecting the LG-NET1 and the LG-NET2
with the BUS form.
