:
The external input priority mode must be set by pressing push button on outdoor unit PCB.
*
2
:
Batch stop or Emergency stop pattern can be selected by pressing push button on outdoor
unit PCB.
*
3
:
The emergency stop function mounted in the equipment does not guarantee the regula-
tions of each country. For this reason, sufficient checking is necessary regarding use. Es-
pecially, 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, communica-
tion error due to noise, VRF external input circuit trouble, etc. must be considered, the pro-
vision of double measures that add direct interruption of the power supply by switch, etc. is
recommended as a precaution.

:
The width of Pulse input signal to CN135 must be 50 ms or more, and the interval of the
signal must be 50
ms or more.
