RWEYQ8~14T9Y1B
VRV IV water-cooled system air conditioner
4P452191-1B – 2020.10
Example Combining the RWEYQ30T9 by using the RWEYQ8T9, RWEYQ10T9, and
RWEYQ12T9.
▪ Minimum circuit ampacity of the RWEYQ8T9=15.5 A
▪ Minimum circuit ampacity of the RWEYQ10T9=16.4 A
▪ Minimum circuit ampacity of the RWEYQ12T9=19.4 A
Accordingly, the minimum circuit ampacity of the
RWEYQ30T9=15.5+16.4+19.4=51.3 A
Multiply the above result by 1.1: (51.3 A×1.1)=56.43 A ⇒ 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.
Transmission wiring can be routed through the front side only. Fix it to the upper
mounting hole.
Fix to the indicated plastic brackets (factory installed).
The wiring from the indoor units must be connected to the F1/F2 (In‑Out)
terminals on the PCB in the outdoor unit.
