NOTES
•
The above Table 3 of Electrical Characteristics refers to one BS unit.
•
See the Engineering data book for other details.
7-4 WIRING EXAMPLE
•
Here is shown a wiring example for one system transmission wiring.
•
Connect terminals F1 and F2 (TO IN/D UNIT) on the control PCB (A1P) in the outside unit Electrical Com-
ponents Box and terminals F1 and F2 (TO OUT/D UNIT) of the control PCB (A1P) of the first BS unit A.
NOTE
1.
Connect cooling-dedicated air conditioners to terminals F1 and F2 (TO OUT/D UNIT) of the final BS unit.
2.
Use 2-core wire for the transmission wiring. Using a multi-core wire with 3 or more cores when two or more
indoor units are used at once could cause abnormal stoppage. (Only use 3-core wire in the COOL/HEAT
SELECTOR.)
3.
Absolutely do not connect the power supply wiring to the transmission wiring terminal block. Doing so
could damage the entire system.
4.
For the transmission wiring, use wire that is within the following ranges. Exceeding these limits could
cause a transmission error.
(1)
Between an outside unit and BS unit,
Between a BS unit and indoor unit, and
Between a BS unit and BS unit
Maximum wiring length: 3280 ft or less
Total wiring length: 6560 ft or less
Branch point max: 16 branch points
(2)
Between a BS unit and COOL/HEAT SELECTOR
Maximum wiring length: 1640 ft or less
