HMI5000P Installation Guide

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 sufficient 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 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.
