Wire modification
(1) Remove insulation from wire at-
tached to wire kit connector.
(2) Remove insulation from field
supplied cable. Use crimp type
insulated butt connector to join field
cable and wire kit wire.
(3) Connect the wire with connecting
wire with solder.
Wiring arrangement
In following figure, all the possible connectors are connected for description.
In actual installation, you cannot connect all the connectors at once.

5.6. External input and external output (Optional parts)
In this setting, you need to remove the front panel. Refer to "8. FRONT PANEL REMOVAL
AND INSTALLATION".
5.6.1 External input
• Indoor unit can be Operation/Stop, Emergency stop or Forced stop by using indoor unit
PCB CNA01 or CNA02.
• "Operation/Stop" mode, "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 192 ft (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.)

IMPORTANT:
Be sure to insulate the connection between the
wires.

● Apply voltage terminal ([CNA01], [CNA03])
When a power supply must be provided at the input device you want to connect, use the
Apply voltage terminal ([CNA01], [CNA03]).

*1: Make the power supply DC 12 to 24 V. Select a power supply capacity with an ample
CNA03
surplus for the connected load.
Do not impress a voltage exceeding 24 V across pins 1-2, and 1-3.
CNA02
*a: The allowable current is DC 5 mA to 10 mA. (Recommended: DC 5 mA)
CNA01
Provide a load resistance such that the current becomes DC 10 mA or less.
Select very low current use contacts (usable at DC 12 V, DC 1 mA or less).
*b: The polarity is [+] for pin 1 and [-] for pin 2 and 3. Connect correctly.
When connected to Apply voltage terminals of multiple indoor units with a connected unit,
be sure to make a branch outside the indoor unit using a pull box, etc. as shown on below
example.

● Dry contact terminal ([CNA02], [CNA04])
When a power supply is unnecessary at the input device you want to connect, use the Dry
contact terminal ([CNA02], [CNA04]).
