Prior to installation, check that the wall is strong enough to
support the weight of the controller to prevent the controller
from falling.

6 Push the wire through the wall hole, and connect the M-NET
transmission cable (centralized control cable that is connected to TB2 of
the power supply unit (PAC-SC51KUA)) to M-NET transmission cable
terminal A, B (both non polarity) and S.
Connect the DC power cable from the power supply unit
(PAC-SC51KUA) to the 24VDC power supply terminal block of the
controller. There is V+ and V- polarity.
NOTE
* If the screw provided for the installation plate, cannot be
used because of the wall thickness, use an M4 flathead
screw that matches the wall thickness.
NOTE
* When using an LAN and external signal I/O, refer to section
