12V DC Terminal Block
Bottom View
This 2-pin terminal block is considered a low power solution. Connect a DC power cord to this
terminal block by inserting the wire into the block and then screw tight the screw on top to
secure the wire in place. Please make sure the positive and negative wires are installed cor-
rectly. Using a voltage more than the recommended range may fail to boot the system or
cause damage to the system board.
Note:
An optional DC cable converter can be purchased to convert the 2-pin terminal
block to a coaxial DC jack.
Important:
Insufficient power supplied to the system may result in instability or malfunction
of the add-in boards and peripherals. Calculating the system's approximate power
usage is important to ensure that the power supply meets the system's consump-
tion requirements.
