12.6 How to Install
1. Choose a place in which to install the remote controller (switch box).
Be sure to observe the following steps:
(1) When installing on either the switch box or the wall, allow extra space around the remote controller as
shown in the figure at the right.
(2) Parts which must be supplied on site.
• Switch box for two units
• Thin-copper wiring pipe
• Lock nut and bushing
• Surface raceways
Construction precautions
• Do not connect a wire exceeding the specified thickness to the terminal block. (This can lead to damage.)
• Do not run together with other wiring in a wiring conduit. (This can cause communication errors.)
• Do not connect multiple communication lines using a single multicore cable. (This can cause
communication errors.)
• The total length of the communication line must be 500 m or less. (This can cause communication errors.)
2. Seal the remote controller cord with putty in order to prevent the possible entry of dew, water droplets, cockroaches, other insects, etc.
When using the switch box
• When installing on the switch box, seal the
connections between the switch box and wiring
pipe with putty.

• Insert a flathead screwdriver into one of the open slots and move the screwdriver in the arrow direction.
CAUTION • Remove the cover carefully so as to avoid any damage.
• Do not turn the screwdriver in the slot. Doing so may
damage the slot.
4. Install the lower case on the switch box or directly on the wall.

CAUTION Do not tighten the screws too tight. Doing so may deform or crack the lower cover.
NOTE: • Choose a flat plane for installation.
• Fasten the switch box at more than two places when installing directly on the wall.
• When reinstalling on the wall, fasten securely using anchors.
5. Connect the remote control cord to the remote controller terminal block.
For the remote control, obtain a 2-core cable
between 0.3 and 1.25 mm
CAUTION Do not use crimp terminals to connect to remote controller terminal blocks. The terminals may contact the board and
cause trouble or contact the cover and damage the cover.
CAUTION Prevent remote cord chips from getting into the remote controller. Electric shock or malfunction may result.

When installing directly on the wall
• When opening a hole using a drill for the remote controller cord (or when taking the cord out
of the back of the remote controller), seal the hole with putty.
• When routing the cord via the portion cut off from the upper cover, similarly seal that portion
with putty.
• When taking the remote controller cord from back of the controller, use surface raceways.
