Connecting the Antminer T21 PDU125-12AC1 to Goldshell and Bitmain Mining Equipment
Now that we’ve covered the basics, let’s walk through the steps to connect the Antminer T21 PDU125-12AC1 to Goldshell and Bitmain mining devices.
Step 1: Prepare Your Setup
Before connecting the PDU, ensure that your mining facility’s electrical infrastructure can support the PDU’s input requirements. Verify the following:
- The power supply matches the PDU’s input voltage range (346-480V AC).
- The circuit breaker capacity is sufficient for the PDU’s 125A input current.
- Proper grounding is in place to ensure safety.
Step 2: Install the PDU
Mount the PDU in a secure location within your mining rack or facility. Ensure adequate ventilation to prevent overheating, as mining environments can generate significant heat.
Step 3: Connect the Power Input
Using appropriate cables, connect the PDU to your facility’s power source. Ensure the connections are secure and comply with local electrical codes. The PDU’s three-phase + neutral + protective earth configuration provides a stable and safe power supply.
Step 4: Connect Goldshell Mining Devices
Goldshell miners typically operate on single-phase power. To connect them to the PDU:
- Use the PDU’s single-phase output ports (200-227V).
- Plug the Goldshell miner’s power cable into the PDU’s 6-pin connector.
- Ensure the miner’s power requirements match the PDU’s output specifications.
Step 5: Connect Bitmain Mining Devices
Bitmain miners, such as the Antminer series, often require three-phase power. To connect them:
- Use the PDU’s three-phase output ports (346-480V).
- Plug the Bitmain miner’s power cable into the PDU’s 6-pin connector.
- Verify that the miner’s power consumption aligns with the PDU’s capacity.
Step 6: Test and Monitor
Once all connections are made, power on the PDU and your mining devices. Monitor the system for any irregularities, such as overheating or voltage fluctuations. The PDU’s built-in protection features will help mitigate potential issues.
