6.5   ATTACHMENT OF CORNER COVER WITH MOTION SENSOR AND RADIATION SENSOR 
ON THE AIR PANEL MODEL P-AP160NAE2
? NOTE
•  Pay attention that the detecting function will be decreased if the lens 
for motion sensor smudges.
•  In this case, wipe off smudges by a cotton swab soaked alcohol 
(Isopropyl alcohol is recommended) or a soft cloth.
•  When wiping off smudges on the lens for motion sensor, do not apply 
excessive force.
•  If excessive force is applied, the resin lens may be damaged so that 
may cause malfunctions such as misdetection or undetectable of the 
motion.
a.  The corner cover with sensor can be attached to any of 
corners (three directions, Ⓐ , Ⓑ and Ⓓ). Determine the 
best location in line with user's requirements.
? NOTE
•  The corner cover encasing the Motion Sensor should be placed in the 
corner closest to the wired controller.
•  Do not attach at location Ⓒ.
•  When the Motion Sensor is attached at location Ⓐ, control setting on 
the wired controller is not necessary.

? NOTE
•  In the RCI-FSR1 4-way cassette indoor unit where the PCB number 
PI1942 is mounted, a patch cord inserted into the CN33 connector is 
supplied. This patch cord will be used to connect the motion sensor 
of the panel P-AP160NAE2 to the indoor unit PCB.
•  The CN10 connector is only available for connection of the Motion 
Sensor kit SOR-MSK and for panels P-N23NA2, and P-AP160KA3.
c.  Run the connecting cable from CN33 to the corner cover 
with motion sensor through top of the mounting plate. 
Then measure the distance 100mm to 200mm from the 
corner cover to the relay connector as shown below.
