Hydro Box; Idu - Gree GMV-S120WL/A-S Service Manual

Model
GMV-S224W/A-X 380V 3N～50Hz
GMV-S280W/A-X 380V 3N～50Hz
Note:
① The circuit breaker must support magnetic release and thermal release at the same time
to protect the system from short circuit and overload.
② The power cable specification means the selected specification when BV single-core
wire(2~4 pcs) goes through plastic pipe in ambient temperature of 40° C and the circuit
breaker operates in 40° C. If the actual installation condition changes, please refer to the
instruction manual for power cable and circuit breaker provided by the manufacturer.
③ The circuit breaker shall adopt D type circuit breaker.
④ The sectional area of a wire is applicable for a distance range of up to 15 m. If the
distance is greater than 15 m, increase the sectional area of the wire correspondingly to
prevent the wire from being burned due to overload current and to avoid fire.

12.2.2.2 Hydro box

The circuit breaker and power cable diameter of hydro box can refer to the following table:
Model
NRQD16G/A-S
Note:
① The power cable must be copper cable with operation temperature not higher than the
specified value.
② If the length of power cable is longer than 15m, please increase the sectional area of
power cable in order to avoid hazards caused by overload.
③ The power cable specification means the selected specification when BV single-core
wire(2~4 pcs) goes through plastic pipe in ambient temperature of 40° C and the circuit
breaker operates in 40° C. The circuit breaker shall adopt D type circuit breaker.
④ If the actual installation condition changes, please refer to the instruction manual for
power cable and circuit breaker provided by the manufacturer.
