The HMIZHAT7W1 is a panel cutout adapter from the Schneider Electric Harmony P6 series, designed to mount a 15-inch wide display module into a cutout originally sized for a Harmony GTU 15-inch wide HMI. This is a mechanical adaptation accessory — it bridges the panel opening geometry between two display families so an upgrade or swap doesn't require cutting new sheet metal.
Single unit per package. The adapter fits between the panel cutout and the Harmony P6 display bezel — no wiring or programming involved. Verify the existing cutout dimensions match the Harmony GTU 15-inch wide footprint before ordering; the adapter does not change the display's electrical interface or communication protocol.
