By outlining what you should and shouldn’t do with the Bitmain Antminer E9‘s New PSU, the instructions in this manual will help you use it properly.
Precautions for Use of PSU. This Applies to All APW Series PSU.
12 Do’s to Follow
1. Bitmain Antminer E9 uses APW12 power supply.Purchase a plug that is compatible with your local power outlets and complies with local standards because there are more than a dozen different types of AC power plugs and sockets used throughout the world. We use a C13 cord, which is a standard desktop power cord, for our APW series.
- The power cord must have a minimum 10 A rating.
- Minimum length should be 1.5 meters.
- Cross sectional area of cable’s copper conductor should not be smaller than 1 mm2
2. Check to see if the voltage and outlets in your area can accommodate the needs of the PSU and the Bitmain Antminer E9 miners. The power supply unit’s (PSU) starting voltage must be the same as the output voltage coming from the outlet or socket.
A 210 V to 240 V input voltage range is required for the PSU. The output voltage of the PSU must match the requirements of the Bitmain Antminer E9.
3. Before using, inspect the PSU to make sure it is in good condition and was not damaged during shipping; if it was, it cannot be used.
4. Make sure the PSU is properly grounded and wired.

5. If you don’t want lightning to hurt your equipment, install lightning protection.
6. Install the PSU in a location with unrestricted airflow and no barriers.
7. To significantly extend the PSU’s lifespan, lower the power output.
- The PSU’s rated power should not be loaded with more power than 90% of that.
8. Maintain a PSU temperature of less than 50 °C. The half life of the PSU is reduced by 10% for every 10 degrees Celsius increase in temperature.
9. Utilizing the positive and negative ports of D/C power 6-pin connectors, properly connect the Bitmain Antminer E9 miner‘s hash and control boards.
*NOTE: Yellow – Positive; Black – Negative
10. Make sure the power cables are firmly fastened at the PSU terminal as well.
11. The power supply requires two power cords for Bitmain Antminer E9. If both power outlets are needed to deliver power simultaneously, the power supply can output. If only one is inserted, the power supply has no output.
12. The APW12 power supply is split into two power supply standards, referred to as APW12-1215a/b/c and APW12-1417a/b/c, which are distinguishable by the model. They are not interchangeable. Do not forget to bring an adapter when changing the power source.
5 Don’ts to Follow
1. Avoid connecting or disconnecting the power connectors while the power supply unit is on. Make sure the power is off before plugging in or unplugging. Voltaic arcs caused by excessive DC can damage DC output terminals and pose a fire risk.
2. Outside of small spaces, use the PSU. Anything that might restrict the PSU’s airflow is prohibited.
3. Additionally, the PSU cannot be used in environments with high levels of humidity, salt in the air, or condensation.
4. Never attempt to power a PSU that appears to be damaged.
5. Never try to disassemble or repair the PSU yourself. Investigate further or return the PSU to us for repair if you notice any problems with it.
