(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 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]).

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 DC5~10mA. (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.

• No voltage terminal ([CN17])
When a power supply is unnecessary at the input device you
want to connect, use the no voltage terminal ([CN17]).

careful when wiring.
When connected to no voltage terminals of multiple indoor
units with a connected unit, insulate each indoor unit with
relay, etc. as shown on below example.
When connected to multiple indoor units directly, it will cause
breakdown.

Operation behavior
• Input signal type
The input signal type can be selected.
Pulse
Edge
The width of pulse
must be longer than
200msec.
It is switched by Dip-sw on the indoor
unit PCB.
