This article describes how to fix the Bitmain Antminer S17 power supply voltage is unstable issue.
The hash board of the Antminer S17 will automatically shut down if the voltage is unstable while it is operating (as shown below), which will prevent the miner from mining normally.
Troubleshooting:
Method 1: Check to see if the Antminer’s power cable is loose; re-plug or use a new power cable as needed.
Method 2: Use the Fluke 15B+ multimeter to check whether the miner’s power supply voltage reaches the standard voltage for the normal operation of the Antminer S17. It is advised to swap out the new APW9 power supply if it falls below the required voltage.

Method 3: Verify that the miner is properly grounded. The voltage of the miner will also be unstable if the miner is improperly grounded.
Method of detection: Set the Fluke 15b+ multimeter to A/C 220V. Place the multimeter’s leads on the exposed area of the miner’s aluminum body or casing and metal frame while it is operating. The miner is not grounded or the grounding is done incorrectly if it is discovered that there is a voltage passing through.
