QTERM-G72 Terminal Installing to NEMA-4X Specifications
Qlarity-Based Terminal Hardware 93
7.4.1 Cutting Out for Panel Mount
The QTERM-G72 terminal can be mounted in panels from 0.8 to 12 mm thick. No screw holes
need to be drilled to install the terminal in the panel. Make a rectangular hole in the panel
using the following dimensions.
Figure 38 is a diagram of the landscape cutout.
File any rough edges smooth, especially on the face of the panel.

Use of an anti-static strap is recommended when performing installation and maintenance.
1. Verify that the panel surface around the cutout is clean and free of rough edges. A gasket
built into the terminal seals against the panel surface. Dirt or imperfections on the panel
may prevent a proper seal. To achieve a NEMA-4X seal, the panel must maintain a flat-
ness of no greater than 1 mm overall and no greater than .05 mm/mm locally. Addition-
ally, a Ra surface roughness of 1.6 µm must not be exceeded (standard NEMA-4
enclosures).
2. Place the terminal into the panel cutout and verify that the terminal is oriented correctly.
The Beijer Electronics logo on the front panel, if included, or the printed labels on the
back panel may indicate the orientation. If not, you can determine which side should be at
the top by the position of the serial port(s) on the back panel as follows:
