Electrical installation requirement
- This miner requires a compatible three-phase electrical supply. Verify the specified voltage, circuit protection, grounding and power connector with a qualified electrician before installation.
- Do not connect this equipment to a standard single-phase household outlet unless the manufacturer explicitly specifies a compatible configuration.
Hydro installation requirements
- Radiator / external cooling loop is required unless the installation already provides a compatible heat-rejection system.
- Verify coolant quality, flow, pressure, leak testing and electrical provisioning before operation.
Notes
- Actual hashrate, efficiency, acoustics and power draw vary with coolant temperature, ambient conditions, firmware and electrical configuration.
- Ensure adequate hydraulic capacity, leak testing and electrical provisioning for the specific installation.
- Mining output varies with network conditions, pool performance and uptime.
