MiniCom (OP6800) User's Manual

> ## 6. Installation and Mounting Guidelines

> Chapter 6 describes some considerations for mounting the OP6800 in a panel, and includes detailed mounting instructions.

> ### 6.1 Installation Guidelines

> When possible, following these guidelines when mounting an OP6800.

> 1. Leave sufficient ventilation space.
> 2. Do not install the OP6800 directly above machinery that radiates a lot of heat (for example, heaters, transformers, and high-power resistors).
> 3. Leave at least 8" (20 cm) distance from electric power lines and even more from high-voltage devices.
> 4. When installing the OP6800 near devices with strong electrical or magnetic fields (such as solenoids), allow a least 3" (8 cm), more if necessary.

> The OP6800 has strong environmental resistance and high reliability, but you can maximize system reliability by avoiding or eliminating the following conditions at the installation site.

> - Abrupt temperature changes and condensation
> - Ambient temperatures exceeding a range of 0°C to 50°C
> - Relative humidity exceeding a range of 5% to 95%
> - Strong magnetism or high voltage
> - Corrosive gasses
> - Direct vibration or shock
> - Excessive iron dust or salt
> - Spray from harsh chemicals

> ### 6.2 Mounting Instructions

> A bezel and a gasket are included with the OP6800. When properly mounted in a panel, the bezel of the OP6800 is designed to meet NEMA 4 specifications for water resistance.

> Since the OP6800 employs an LCD display, the viewing angle must be considered when mounting the display. Install the OP6800 at a height and angle that makes it easy for the operator to see the screen.

> #### 6.2.1 Bezel-Mount Installation

> This section describes and illustrates how to bezel-mount the OP6800. Follow these steps for bezel-mount installation.

> 1. Cut mounting holes in the mounting panel in accordance with the recommended dimensions in Figure 19, then use the bezel faceplate to mount the OP6800 onto the panel.
> Figure 19. Recommended Cutout Dimensions

> 2. Remove the standoffs added to the OP6800 as described in Chapter 2, "Getting Started." The standoffs were used to prop up the OP6800 beside the Demonstration Board, and are not needed to mount the OP6800.

> 3. Carefully "drop in" the OP6800 with the bezel and gasket attached.

> 4. Fasten the unit with the four 4-40 screws and washers included with the OP6800. If your panel is thick, use a 4-40 screw that is approximately 3/16" (5 mm) longer than the thickness of the panel.

> Carefully tighten the screws until the gasket is compressed and the plastic bezel faceplate is touching the panel.

> Do not tighten each screw fully before moving on to the next screw. Apply only one or two turns to each screw in sequence until all are tightened manually as far as they can be so that the gasket is compressed and the plastic bezel faceplate is touching the panel.
