• 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 (22 AWG) 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 termi-
nals 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]).
