Connecting a DGE601A52
DGE601A51 only
If the system needs to control many air conditioners, use DGE601A52 to connect them.
You can connect up to 64 air conditioners to 1 DIII port. Because it is possible to connect
to 2 ports on 1 DGE601A51, the number of indoor units you can control with 1 DGE601A51
is up to 128.
By using DGE601A52 or DGE601A53, you can add 64 indoor units.
Using all 8 DIII ports, you can connect and control a total of 512 indoor units at maximum.
WARNING
•
Be sure to perform the operation during power-off conditions. Not doing so
may cause an electric shock.
•
Do not clamp high-current cables together with low-current cables.
