2.2 Choosing a Mounting Location

The DSM250 is housed in a waterproof enclosure (IEC IP67 rating – protected against the effects of temporary immersion in water) and can be mounted in either an outdoor location or an indoor location.

2.3 Mounting the DSM250

The DSM250 has three mounting options, which includes surface mounting, flush mounting, or an optional gimbal mounting. Maretron suggests a location at which the display can be viewed from a relatively straight angle, and at which the keys are easily pressed.

2.3.1 Surface Mounting the DSM250

The DSM250 can be directly mounted to any suitable surface as shown in Figure 1. The steps for this

type of mounting are as follows:

1. Attach the Surface Mount Template (see Section 0) to the surface where the DSM250 is to be

located. a. Make sure the template is level by using one of the horizontal lines as a guide. b. Scotch tape works well for securing the template. c. The maximum thickness of the mounting material should not exceed 1¼” using the provided mounting studs, thicker surfaces can be accommodated but you will need to purchase longer studs.

2. Drill the four mounting holes all the way through the mounting surface at the locations indicated on the Surface Mount Template. a. Use a 3/16” drill bit.

3. Drill or cut a single hole for the electrical connector. a. Use a 2¼” hole saw. b. You will probably want this hole to be large enough for your fingers so that you can connect or disconnect the cable without removing the DSM250.

4. Remove the template from the mounting surface.

5. Insert the 2” studs into the back of the DSM250.
