CAUTION
To peel the
fi
lm from the lead cable, use a dedicated tool that will not damage the
conductor cable.
When installing a screw on the terminal block, do not cut the cable by overtightening
the screw. On the other hand, an undertightened screw can cause faulty contact, which
will lead to a communication failure.

xing screws. If the stays are removed, the electric component
box will fall.
If you use as “Floor console”, you must remove screws and RFMs (2 position).
When removing the electric component box, remove the clamp from the cables.
After completing the work, fasten the cables as they were originally by installing the clamp.

CAUTION
Be careful not to pinch the lead cables between the electric component box and
base.
(4) Wiring
* When there is 1 transmission cable or remote controller cable, fasten it the same way as
shown in the
fi
gure with a cable tie (medium).
CAUTION
When switching the DIP switch (SW1), be sure to turn off the power supply to the
indoor unit. Otherwise, the PC board of the indoor unit may be damaged.

(1) External input
• Indoor unit can be Operation/Stop or Emergency stop or Forced stop by using indoor
unit PCB CNA01 or CNA02.
• “Start/Stop” mode or “Emergency stop” mode or “Forced stop” mode can be selected
with function setting of indoor unit.
• Indoor unit can be Forced thermostat off by using indoor unit PCB CNA03 or CNA04.
• A twisted pair cable (22 AWG) should be used. Maximum length of cable is 150 m.
• Use an external input and output cable with appropriate external dimension, depending
on the number of cables to be installed.
• The wire connection should be separate from the power cable line.
Input select
Use either one of these types of terminal according to the application. (Both types of
terminals cannot be used simultaneously.)
