(1) External input terminals
• Indoor unit can be Start/Stop or Emergency stop, Forced stop by using indoor unit PCB
CN6 or CN17.
Wiring methods and speci
fi
cations
• A twisted pair cable (22AWG) 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.
• The wire connection should be separate from the power cable line.
• Input selection
Use either one of these types of terminal according to the
application. (Both types of terminals cannot be used simultaneously.)
• Voltage terminal ([CN6])
When a power supply must be provided at the input device you want to connect, use the
voltage terminal ([CN6]).

*1 Make the power supply DC12 to 24V. Select a power supply capacity with an ample
surplus for the connected load.
Do not impress a voltage exceeding 24V across pins 1-2, and 1-3.
*a The allowable current is DC5 to 10mA. (Recommended: DC5mA)
Provide a load resistance such that the current becomes DC10mA or less.
Select very low current use contacts (usable at DC12V, DC1mA or less).
*b The polarity is [+] for pin 1 and [-] for pin 2 and 3.
Connect
correctly.
When connected to voltage terminals of multiple indoor units with a connected unit, be
sure to make a branch outside the indoor unit using a pull box, etc. as shown on below
example.
