Panel Preparation

To provide a NEMA 4 seal, a metal panel or mounting surface that does 
not flex more than 0.010” is required. Thin panels or surfaces may bow 
between the mounting clamps and not form a seal with the gasket.

Allow enough clearance around the unit for the mounting hardware and 
cable connections. Cutout dimensions for each particular HMI model are 
available for print and download from the Support Center-Dimensional 
Drawings section of the Maple Systems website.

The area of the panel or mounting surface where the gasket comes into 
contact must be flat and free of scratches, pits, and other features that 
prevent the gasket from sealing properly. If the panel or mounting 
surface is not uniform, thick, flat, stiff, or smooth enough, then a sealant 
such as silicone may be required.

Note:

  Clean and deburr the panel cutout before the HMI is installed.

Mount the HMI to the Panel

Note:

 The clamps for some models may be slightly different than 

shown here, but operate essentially the same way.

Steps:

1. Prepare the clamps for the HMI by inserting the screws into the 

clamp as shown above. Position the screws so that the ends don’t 
protrude past the clamp edge.

2. Set the HMI in the panel cutout and hold it in place until all clamps 

are in position.

3. Tighten the screw clamps in an even pattern until the unit is secure. 

Recommended torque: 

3.5 in/lbs

. 

Caution:

  Do not over-tighten the screws; the overlay may warp 

or the housing may get damaged.
