NOTE:
(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, 10 A per wire.
(2-3) NEM: Normal Energy Mode; HEM: High Energy Mode.
(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.
