Note
Provide a single ground point by grounding the shield wire of the M-NET centralized controller transmission cable at the
power supply unit. Provide a ground point for the indoor-outdoor transmission cable for each outdoor unit. (Provide the
appropriate grounding according to the local standard.)
Set the centralized control switch (SW2-1) on the outdoor unit connected to the M-NET transmission cable to ON.
To prevent unauthorized access, always use a security device such as a VPN router when connecting the EB-50 to the
Internet.
When connecting BAC-HD150 (BM ADAPTER), AT-50, or GB-50ADA to the EB-50 in the same M-NET system, certain
restrictions apply. Consult your dealer for details.
