AMX Modero NXD-500i - Manual (Page 18)

Installation
12 NXD-500i 5" Wall/Flush Mount Touch Panel with Intercom
Installing the NXD-500i into drywall
Unlike most AMX touchpanels, the NXD-500i comes with a clear plastic backbox (FIG. 7) designed to
attach the panel to standard drywall. This backbox has a locking tab on three of the four faces (missing
only on the face containing the space for the connections) to help lock the backbox to the wall. These
locking tabs are only extended AFTER the backbox is inserted into the wall.
Refer to the diagram for detailed installation dimensions as shown in FIG. 8.
Cutting out the surface slightly smaller than what is outlined in the installation drawings, in
order to make any necessary cutout adjustments, is highly recommended.
1. Prepare the area by removing any screws or nails from the drywall before beginning the cutout
process.
2. Cut out the surface for the back box. Refer to the dimensions in FIG. 8 for more information.

When installing the backbox, make absolutely sure that the assembly is in the correct
position and in the correct place. Once the locking tabs are extended and locked into
place, removing the backbox will be very difficult without having access to the back of
the wall itself or damaging the wall.
