4. Electrical work
• Remote switch Type A (4 bit - 8 setting)/Type B (1 bit - 1 setting)
Demand control is available by connecting remote switches with terminal No.10 - 14.
Make sure to use the non-voltage switch (for the remote switch)
Remote switch cable length : Maximum 10m
Remote switch : Minimum applicable load 12V DC, 1mA
• 4-20mA / 1-5V / 0-10V / 0-10kΩ
1
Use 4-20mA / 1-5V / 0-10V
Connect the transmission cables to No. 11 and 12 on the terminal block (TB61).
No. 11 on the terminal block(TB62) : Plus side
No. 12 on the terminal block(TB62) : Minus side (Reference side)
2
Use variable resistor (0-10kΩ)
Connect the transmission cables to No. 9 and 10 on the terminal block (TB61).
Note:
The values of the "capacity setting" table on the previous page show the center
of the input value.
Cable length: Maximum 10m

Note:
• External output signals are separated by basic insulation from other circuit
of interface.
• When intelligent multiple outdoor unit control function is selected, OUT2, OUT3,
OUT4, OUT7 and OUT8 will work individually on each interface.
Caution: When 2 or more external outputs are used, the power supply on
the output side should be the same.
Note:
When using IN1 with intelligent multiple outdoor unit control function, input
IN1 to the interface unit respectively. Input IN2 to the main interface which con
-
nects to the ref. address 0 outdoor unit.
Caution:
The external input signals are separated by basic insulation from power sup
-
ply for the unit.
The external input signals should be separated by supplementary insulation
from where user may touch in case that it is installed where user may touch.
Connect the terminals by using the ring terminals and also insulate the ca
-
bles of adjoining terminals when wiring to terminal block.
