What is the power connection on the M251?

Issue:
Where to connect the power to the M251?

Product Line:
M251

Environment:
All serial numbers

Cause:
Need to remove power for Clone process on M251

Resolution:
The M251 can be powered by using the two methods below:

Power supply
The M251 Logic Controller has a 24 Vdc power supply. It also has a removable screw terminal block with three terminals for connecting the power supply.

USB Mini-B port
The M251 Logic Controller can be powered through the USB Mini-B port to perform limited operations. However, a diode mechanism prevents the logic controller from being powered by both the USB and the normal power supply at the same time.
