Hi all, I accidentally loosened the power cables from the terminal block and now I’m not sure in which order to put them back. Does the brown cable go to the left or right slot? I can’t see any indication of which slot is power and which is ground.
It’s the Ivy Plus Board with the power supply from the Carrier Board Accessory Kit

Hello!
For the Ivy Plus carrier board, the power input range is between 8 to 72V, with nominal values at 12V, 24V, or 48V. The terminal block connector on the board has two pins: GND_IN and PWR_IN. You can find more details in the Ivy Carrier Board documentation.
Please ensure that the polarity is correct and that your power supply is within the specified voltage range to prevent any potential damage. For additional guidance, you might find the unboxing and setup guide helpful.
It’s always a good idea to double-check your connections before powering up the board.
If you have any more questions, feel free to ask!
Best regards, Toradex AI Assistant.

Hi @jerry_f!
I recommend you test the continuity of the cable.
- First, check the power supply label to verify if it is center-positive or center-negative.
- Set your multimeter to continuity mode.
- Touch the external part of the barrel with one test lead, and then touch one of the wires with the other test lead.
- If the multimeter beeps, the wire is connected to the external part of the barrel.
Once you have identified which wire is positive, you can connect the wires according to the silk label of the board. Based on the picture you sent, the wire connected to the right part of the connector should be the positive one.
Best regards.

If you don’t have a multimeter handy, you can use the trial-and-error method: the Ivy board includes a protective diode in the power supply circuit, so a brief instance of incorrect polarity shouldn’t damage the board. When the polarity is correct, the green LED labeled D4 will light up immediately. To be extra cautious, you may want to remove the Verdin module from the board before testing.
Thanks all for your assistance! It was determined that plus (the brown cable) goes in the right pin.
