Be sure to use one side of a twisted-pair cable when using transmission cable with 2 sets
of twisted-pair cables.
Wind with insulation tape to prevent short circuit
Use one side of the
twisted-pair cable
Connect both ends of shielded wire to earth.

CAUTION
Do not bundle the cable for base heater with other cables.
When connecting cable to Input2
Cable (for external input and output)
Cable tie (tightened with transmission cable)
Cable (for external input and output)
* If the outdoor unit is not installed in the wall, cover the exposed part of cable
with a 1 mm thick or more insulation tubing.
6. 6. 2. External input terminal
• Setting to low noise mode, cooling priority/heating priority selection, outdoor unit
operation peak control setting, emergency/batch stop and electricity meter pulse are
possible from the outside.
Wiring method and specifi cations
* A twisted pair cable (0.33mm
2
(22AWG)) should be used. Maximum length of cable is
150m.
* Use an external input and output cable with appropriate external dimension, depend-
ing on the number of cables to be installed
* For each input, pin No.1 is of positive polarity and pin No.2 is of ground level.

The operations of each input terminal and the selection of function are set with the push button
on the PC board of outdoor unit. About the setting, please refer to “7.4. Push button setting”.
NOTE:
*1:
The “external input priority mode” must be set by pressing push button on PC
board of outdoor unit. (Refer to “7. FIELD SETTING”.)
*2:
Batch stop or Emergency stop pattern can be selected by outdoor unit PC board
push button. (Refer to “7. FIELD SETTING”.)
*3:
The emergency stop function mounted in the J-II does not guarantee the regulations
of each country. For this reason, suffi cient checking is necessary regarding use.
Especially, since the fact that the equipment may not be emergency-stopped in the
case of breaking of the wiring to the external input terminals and communication
line, communication error due to noise, VRF external input circuit trouble, etc. must
be considered, the provision of double measures that add direct interruption of the
power supply by switch, etc. is recommended as a precaution.
*4:
Pulse input to CN135 must be width 50ms or more, and must be interval 50ms or more.
