6.5.3. Connection methods
Wire modification for External
input/output wire
(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.

Status contents
Lit when the power is turned on.
There is a fault with the communication board or the
main board.
The indoor unit is turned off and power is supplied
from the External power supply unit (optional) to the
indoor unit PCB.
IMPORTANT:
Be sure to insulate the connection between the
wires.
Locally
Wire kit connector
purchased
(optional parts)
Solder and insulate the connected parts.
Wiring arrangement
In following figure, all the possible connectors are connected for description.
In actual installation, you cannot connect all the connectors at once.
Cable clamp
Cable of the IR receiver unit
Once all connectors required for
connection are connected, push
up the circuit board that was
pulled down, and endure that
the hooks are in place.
Fix the connected cables by
passing them through the hole
using the grille accessory, cable
tie, as shown in the following
figure.
6.6. External input and external output (Optional parts)
6.6.1. 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 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.)
● 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]).

Connected unit
*1: Make the power supply DC12 to 24V. Select a power supply capacity with an ample
surplus for the connected load.
Do not impress a voltage exceeding 24V across pins 1-2, and 1-3.
*a: The allowable current is DC 5mA to 10mA. (Recommended: DC5mA)
Provide a load resistance such that the current becomes DC10mA or less.
Select very low current use contacts (usable at DC12V, DC1mA or less).
*b: The polarity is [+] for pin 1 and [-] for pin 2 and 3. Connect correctly.
