Here is a simple step-by-step guide to check if your miner is grounded properly:
- Make sure the miner is not in contact with any metal shelf: This is crucial because any contact could interfere with your measurements.
- Set your multimeter: You should set your multimeter to AC 220V. This is because you’re measuring potential electrical leakage, which would be in AC form if it’s coming from your home or business power supply.
- Test the miner’s body: While the miner is running, place one test lead (probe) of your multimeter on the aluminum body/casing of the miner and the other on the exposed part of the metal shelf.
- If you detect voltage, it suggests that your grounding is not done properly or at all. You need to take immediate action to ground the miner correctly.
- If there is no voltage detected, this indicates that your grounding is effective, and there’s no leakage.
- Ensure the Ethernet port frame is not in contact with the control board panel: Just as with the metal shelf, any contact could influence your measurements.
- Test the Ethernet port frame: While the miner is still running, place one test lead on the aluminum body/casing of the miner and the other on the metal frame of the Ethernet port.
- If voltage is present, it indicates that your grounding is not done properly. You should take immediate action.
- If there’s no voltage detected, it means your grounding is effective and there is no leakage.
Remember, if your miner is not grounded properly, electrical leakage can damage your device over time. Always ensure that your grounding is done correctly, ideally by a professional electrician, to safeguard your miner and prolong its lifespan. Voltage exceeding 1V can damage the miner, while maintaining a voltage below 0.3V is advisable for the long-term health of your miner.
