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.

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
54 in
PCB CNA01 or CNA02.
• "Operation/Stop" mode, "Emergency stop" mode or "Forced stop" mode can be selected
or less
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 492 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.)
● Apply voltage terminal ([CNA01], [CNA03])
