4-2. POWER SUPPLY CABLE WIRING
POWER SUPPLY CABLE SPECIFICATIONS
Use a separate power supply for the outdoor unit and indoor unit.

●
Select the power cable type and size in accordance with local regulations.
●
Select a wire length (Max. wire length) such that the voltage drop is less than 2%.
●
When the wire length is long and voltage drop exceeds this value, increase the wire
diameter to stay within design limits.
z
Indoor unit & RB unit
Refer to the table for the breaker specications of each installation condition. Perform the
power crossover wiring within the range of the same refrigerant system.When the crossover
wiring is done, make a connection for "RB units" and "indoor units" to satisfy conditions Table
A and Table B below.

When the power crossover wiring is done, make it so that the total of the MCA of the
connected "RB units" and "indoor units" does not exceed the 11 A.
NOTE: With Vertical air handler type, connect only one indoor unit to a MAX.CKT.BKR.
(Crossover wiring is prohibited.) Select a minimum of 7 or more multiples of rated current under
the condition time in seconds 10 ms (0.01 S) or less at the current breaker trip curves (time in
seconds/multiples of rated current).
Table B. Ground Fault Equipment Breaker requirements
Breaker capacity Maximum connectable "Units"
30 mA, 0.1 sec or less 36 or less
100 mA, 0.1 sec or less 37 to 121
If the total number of units connected to the breaker exceeds 36, either add a 30mA breaker,
or use breakers with a greater capacity.
