For all models:
▪ Phase and frequency: 3N~ 50 Hz
▪ Voltage: 380~415 V
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=22.0 A
▪ Minimum circuit ampacity of the REYA14=27.0 A
Accordingly, the minimum circuit ampacity of the
REYA24=22.0+27.0=49.0 A
Multiply the above result by 1.1: (49.0 A×1.1)=53.9 A, so the
recommended fuse capacity would be 63 A.
NOTICE
When using residual current operated circuit breakers, be sure to use a high-speed
type 300 mA rated residual operating current.
NOTICE
Sheathed and shielded cables are required for transmission wiring between outdoor
unit and BS unit.
Transmission wiring can be routed through the front side only. Fix it to the upper
mounting hole.
