MCA=Minimum circuit ampacity. Stated values are maximum values.
Please use the table above to specify the requirements for the power
supply wiring.
For non-standard combinations
Calculate the recommended fuse capacity.
Formula Calculate, by adding the minimum circuit amps of each
used unit (according to the table above), multiply the
result by 1.1 and select the next higher recommended
fuse capacity.
Example Combining the REYA24 by using the REYA10 and
REYA14.
▪ Minimum circuit ampacity of the REYA10=22.0A
▪ Minimum circuit ampacity of the REYA14=27.0A
Accordingly, the minimum circuit ampacity of the
REYA24=22.0+27.0=49.0A
Multiply the above result by 1.1: (49.0A×1.1)=53.9A,
so the recommended fuse capacity would be 63A.
NOTICE
When using residual current operated circuit breakers, be
sure to use a high-speed type 300 mA rated residual
operating current.
NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, slightly twist the strands to consolidate the
end of the conductor for either direct use in the terminal
clamp or insertion in a round crimp-style terminal. Details
are described in "Guidelines when connecting the electrical
wiring" in the installer reference guide.
17.3 To route and fix the
interconnection wiring
NOTICE
Sheathed and shielded cables are required for
interconnection wiring between outdoor unit and BS unit.
Interconnection wiring can be routed through the front side only. Fix
it to the upper mounting hole.
