• Operation/Stop, Emergency stop, or Forced stop of the indoor unit can be set by using CNA01 or
CNA02 on the indoor unit PCB.
• Start/Stop mode, Emergency stop mode, or Forced stop mode can be selected with function set-
ting of the indoor unit.
• Forced thermostat off of the indoor unit can be set by using CNA03 or CNA04 on the indoor unit
PCB.
• A twisted pair cable 22 AWG (0.33 mm
2
) should be used. Maximum length of cable is 492 ft (150
m).
• Use an external input and output cable with appropriate external dimension, depending on the
number of cables to be installed.
• When connecting the external input wire, do not route the wire closely to the power cable line.

Use either one of Apply voltage terminal of Dry contact terminal according to the application. (Both
types of terminals cannot be used simultaneously.)
• CNA01, CNA03: Apply voltage terminal
When a power supply must be provided at the input device you want to connect, use the Apply
voltage terminal (CNA01, CNA03).

:
Make the power supply DC12 to 24 V. Select a power supply capacity with an ample sur-
plus for the connected load. Do not impress a voltage exceeding 24
V across pins 1-2,
and 1-3.
*
2
:
The allowable current is DC 5 mA to 10 mA. (Recommended: DC 5 mA)
Select very low current use contacts (usable at DC 12 V, DC 1 mA or less).
*
3
:
The polarity is “+” for pin 1, and “-” for pin 2 and 3. Connect correctly.
