6.7.3 External input terminal
• Setting to low noise mode, outdoor unit operation peak control setting, emergency/batch
stop and electricity meter pulse are possible from the outside.
• Exceptforwattmeterpulsereception(CN135)amongexternalinputterminals,onlythe
primary unit is effective.
Wiring method and specifications
* Atwistedpaircable(0.33mm²(22AWG))shouldbeused.Maximumlengthofcableis
150 m.
* Useanexternalinputandoutputcablewithappropriateexternaldimension,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.

Subordinate unit can connect only input 5 (CN135).
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: Batch stop or Emergency stop pattern can be selected by outdoor unit PC board
push button. (Refer to “7. FIELD SETTING”.)
*2: The emergency stop function mounted in this model 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
caseofbreakingofthewiringtotheexternalinputterminalsandcommunication
line,communicationerrorduetonoise,VRFexternalinputcircuittrouble,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.
*3: Pulse input to CN135 must be width 50 ms or more, and must be interval 50 ms or
more.
