External input terminal6. 7. 2.
Service parts: EXTERNAL INPUT WIRE A (9368777005)
Setting to low noise mode, outdoor unit operation peak control setting, emergency/•
batch stop and electricity meter pulse are possible from the outside.
Except for wattmeter pulse reception (CN135) among external input terminals, only •
the Master unit is effective.
Wiring method and specifi cations
A twisted pair cable (0.33 mm*
2
(22AWG)) should be used. Maximum length of
cable is 150 m.
Use an external input and output cable with appropriate external dimension, de-*
pending 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.*

Slave unit can connect only input5 (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 button setting.
Note :
*1: Batch stop or Emergency stop pattern can be selected by outdoor unit PC
board push button.
*2: The emergency stop function mounted in the V-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 com-
munication 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.
*3: Pulse input to CN135 must be width 50ms or more, and must be interval 50ms
or more.
