Print Page(1) External input terminals
• Indoor unit can be Start/Stop or Emergency stop by using indoor unit PCB CN9.
Wiring methods and specifications
• A twisted pair cable (22AWG) should be used. Maximum length of cable is 82 ft. (25 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.
• Open circuit voltage : ≤ 5.25 (V).
• Short circuit current : ≤ 0.6 (mA).
• Short circuit detection resistance (R ON ) : ≤ 500 (ohm).
• Short circuit detection resistance (R OFF ) : ≥ 100 (kilo-ohm).

connected unit
* Select very low current use contacts (usable at DC12V, DC1mA or less).
When connected to no voltage terminals of multiple indoor units with a connected unit,
insulate each indoor unit with
relay, etc. as shown on below example.
When connected to multiple indoor units directly, it will cause breakdown.

* When the forced stop is triggered, indoor unit stops and Start/Stop operation by a
remote controller is restricted.
* When forced stop function is used with forming a remote controller group,
connect the same equipment to each indoor unit within the group.
• Selection method of functions
"Start/Stop" mode or "Emergency stop" , "Forced stop" mode can be selected with
function setting of indoor unit.
(2) External output terminals
• When picking up output signals for operating status, abnormal conditions or indoor unit
status.
Wiring methods and specifications
* A twisted pair cable (22AWG) 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.
