Important Connector Polarity Note

Always verify the connector polarity before installing the replacement fan. It is not uncommon for replacement fans to use the same physical connector while having the positive and negative wires installed in different connector positions.

Compare the wire positions, connector orientation, and polarity of the replacement fan with the original fan before applying power. Do not assume that matching wire colors or matching connector shapes automatically indicate the same pin configuration.

If the positive and negative wires are positioned differently, the connector may need to be correctly repinned before installation. Incorrect polarity can prevent the fan from operating and may create a risk to the connected equipment. Connector inspection or repinning should be performed only with the equipment disconnected from power.

⚙️ Fit Notes

• Confirm that the equipment requires 24V DC.
• Verify that the available mounting space supports a 119mm x 119mm x 25mm fan.
• Current markings may vary between 0.29A, 0.36A, and 0.38A depending on production and equipment configuration.
• Compare the connector shape, connector pin positions, lead length, mounting holes, and airflow direction with the original fan.
• Confirm that the fan’s airflow arrow points in the same direction as the fan being replaced.
