(1-1) The hashrate value, Power on wall, and Power efficiency on wall are all typical values. The actual hashrate value fluctuates by ±3%, and the actual Power on wall and Power efficiency on wall fluctuate by ±5%.
(1-2) Inlet water temperature.
(2-1) Caution: Wrong input voltage may cause server damaged.
(2-2) Three-phase AC input, 12A max.
(2-3) If the inlet water temperature is lower than 20 °C, the miner cannot be started. For the external dry cooler (EC2-DT),

• if the outlet water temperature is 35°C, the maximum ambient temperature is 30°C;

• if the outlet water temperature is 45°C, the maximum ambient temperature is 40°C;

• if the outlet water temperature is 50°C, the maximum ambient temperature is 45°C.
(2-4) If the water conductivity is ≥100 μs/cm, the fluid must be replaced. The water conductivity is less than 20 μs/cm when the system is running at the first time.
