5.3 Wiring for Force Stop Input and for Electric Power Distribution
In order to stop the air-conditioner through force stop input, connect the wiring for force stop input to
the terminals Di1 and COM as shown in the sketch below.
In addition, in order to calculate the electric energy using optional Power Proportional Distribution software,
connect the wiring for electric energy to the terminals Pi and COM as shown in the sketch below.
•
0.75 - 1.25mm
2
vinyl cord or cable with sheath (2 wire) -- up to 150m maximum
• The number of connectable indoor units is up to 64 units maximum,
where the Power Proportional Distribution Card as option is used.
•
The measuring meters to be connected must meet the requirements specified below.
• To be a measuring meter with pulse oscillator. (pulse/kwh)
• Pulse band of 100msec or mores
• Measuring meter which uses semiconductor relay for pulse output
and outputs pulses from non-voltage contact

• Don't clamp these cables together with high voltage cables. Failure to observe this instruction would
cause control error.
• Terminals COM are inter-connected. Connecting to either one is allowed, but the number of cables
connectable to one terminal is limited to 2 pieces.
• Don't connect the power cable to Pi, Di, COM terminal blocks. Wrong connection to these terminal
blocks could result in damage and burning of the centralized control devices and of the electric parts
of the indoor and outdoor units. This is very hazardous. Check each wired cable once more before
turning ON the power switch.
Wiring for force stop input
•
0.75 - 1.25mm
2
vinyl cord or cable with sheath (2 wire) -- up to 150m maximum
• When FORCE-STOP INPUT is kept ON, the indoor units connected
thereto are unable to be operated because they are force-stopped.
•
Use a contact which can guarantee minimum application load DC16V and 10mA.
•
Use an instantaneous contact of 200msec or more in current feed time, where required.
