Notes:

(1-1) The Hashrate value, Power on wall, and Power efficiency on wall are all typical value. The actual Hashrate value fluctuates by ±3%, and the actual Power on wall and Power efficiency on wall fluctuate by ±5%.
(1-2) Ambient temperature of 25℃ equals to inlet oil temperature of 30℃
(2-1) Caution: Wrong input voltage may cause server damage.
(2-2) Three-phase AC input, 10 A per wire.
(2-3) Caution: It is strongly recommended that the power on wall of the miner does not exceed this value.
(2-4) The height consists a height of 44mm for the handle.
(2-5) When the miner is used at an altitude from 900m to 2000m, the highest operating temperature decreases by 1℃ for every increase of 300m.
