Electrical installation and shutdown
The APW12 power supply is integrated as part of the HS3 server. It requires 200–240 V AC, 47–63 Hz, and 20 A. The manual states that the equipment has two power inputs: both power supply sockets must be connected simultaneously for normal operation. To power the server off, switch off all power inputs. The equipment must connect to an earthed mains socket-outlet installed nearby and readily accessible.
Wrong input voltage can damage the miner. Have a qualified person verify the exact HS3/APW12 labels, both input paths, cords and connectors, circuit capacity, protection, conductors, disconnecting means, grounding, ventilation, and applicable requirements before energizing. Cord and connector models are not asserted.
