Adapter Fit

Same cooling capacity and voltage as the N431216G050. Cabinet cutout dimensions differ, so an adapter plate is required to bridge the mounting pattern between the existing opening and the VoltAire AT12RNWXX — so you're not fabricating a new opening. Plan on some fitting work during the swap; we'll spec the exact adapter for your installation at order review.

The red areas show where the openings differ; no adapter plate is available for this pairing. The red areas come from the manufacturer's spec sheet and must be confirmed against your actual unit before cutting.

The red hatching shows where the VoltAire openings extend into cabinet metal; confirm the installation plan with VoltAire before cutting.

Step 1 of 4 Start with the existing N4312 cabinet pattern.

The two manufacturer drawings are centered on each other for visual comparison only, because a shared mounting reference between the two units has not been verified. Verify every opening against your actual unit before any cutting or mounting. This comparison uses the standard AC AT12 footprint; the 48 VDC AT12RB has different dimensions. This comparison is a visual guide, not a cutting or drilling template. Openings can vary with voltage and production run — verify against your actual unit before any cutting or mounting, and follow the manufacturer's installation template.
