Remove 2 screws, and remove the base plate 2 from the switch box 3.
Set the 2 screws aside, as they will be used in the section on "4-1. Mounting
the Base Plate" under "Mounting the Centralized Controller".

Insert the switch box 3 into the wall. Size the hole in the wall to ensure that
there is go gap between the switch box 3 and the wall surface.
Use the switch box 3 wall installation dimensions and opening dimensions
shown in the figure below.

Feed the power supply wire B, connection wire C, and ground wire from
inside of the wall, and pull them through the switch box 3 into the room
about 150 mm.
In addition, when not using a conduit for a connection wire C, be sure to install a rubber seal (large) 5 or rubber seal (small)
6 into the hole in the switch box 3 before feeding the connection wire C through the hole.
Use the PG connection E prepared at the installation site to secure the power supply wire B in the hole in the switch box 3.
