External Input And External Output - Fujitsu AOU36RLAVS4 Installation Manual

Shielding the transmission cable
Connect both ends of the shielded
wire of the transmission cable to
the earth (ground) terminal of the
equipment or to the earth (ground)
screw near the terminal.
Be sure to use one side of a
twisted-pair cable when using
Use one side
transmission cable with 2 sets of
of the twisted-
twisted-pair cables.

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.

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 1/16 in (1 mm) thick or more insulation tubing.
Wiring method and specifications
* A twisted pair cable (22 AWG (0.33 mm²)) 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
* 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 but-
ton setting".
NOTES:
*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 regula-
tions of each country. For this reason, sufficient 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 50 ms or more, and must be interval 50 ms or
more.
