5. Install the bottom case.
■ Installation using a switch box
• When installing the bottom case in the switch box, secure at least two cor-
ners of the switch box with screws.
■ Direct wall installation
• Thread the cable through the slot provided.
• When mounting the bottom case on the wall, secure at least two corners of
the remote controller with screws.
• To prevent the bottom case from lifting, use top-left bottom-right corners of
the remote controller (viewed from the front) to secure the bottom case to the
wall with wall plugs or the like.
Caution:
To avoid causing deformation or cracks to the remote controller, do not
overtighten the screws and make an additional installation hole(s).
6. Cut out the cable access hole.
■ Direct wall installation
• Cut out the knockout hole (indicated with grey in <Fig. 4.3.7>) in the front
cover by knife or nipper.
• Thread the remote controller cable from the slot behind the bottom case
through this access hole.
7. Plug the lead wire cable into the top case.
Plug the lead wire cable coming from the bottom case into the top case.
Caution:
To avoid failures, do not remove the controller board protective sheet and the
controller board from the top case.
After the cable is plugged into the top case, do not hang the top case as
shown in <Fig. 4.3.8>. Otherwise, the remote controller cable could sever,
which could cause malfunction to the remote controller.
8. Fit the lead wires into the clamps.
Caution:
Hold the wires in place with clamps to prevent excessive strain from being
applied on the terminal block and causing cable breakage.
