(2) After wiring is complete, clamp the remote controller cable, transmission cable and
power supply cable with binder.
For U.S.A. and Canada
For Others
When installing a screw on the terminal block, do not cut the cable by overtightening
the screw. On the other hand, an under tightened screw can cause faulty contact,
which will lead to a communication failure.
(3) Attach the control box cover.

(1) External input terminals
• Indoor unit can be Start/Stop or Emergency stop by using indoor unit PCB CN27.
Wiring methods and specifi cations
• 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.
