2.3 Connecting Hardware 2.3.1 Choosing a Location 2.3.1.1 DIN Rail Mounting The DIN rail mount option is the quickest installation option. Additionally, it optimizes the use of rail space. The metal DIN rail kit is secured to the rear of the serial device server. The device can be mounted onto a standard 35mm (1.37”) x 75mm (3”) height DIN rail. - Page 23 Insert the top back of the mounting bracket over the DIN rail. Push the bottom of the server towards the DIN rail until it snaps into place. DIN Rail Figure 2.8 Installing the DIN-Rail Mounting Kit Removing the DIN-Rail Mounting Kit Push the server down to free the bottom of the plate from the DIN rail.
- Page 24 2.3.1.2 Wall-Mounting The wall mounting option provides better shock and vibration resistance than the DIN rail vertical mount. Note When installing, make sure to allow for enough space to properly install the cabling. Before the device can be mounted on a wall, you will need to remove the DIN rail plate.
- Page 25 Locate the installation site and place the server against the wall, making sure it is the final installation location. Use the wall mount plates as a guide to mark the locations of the screw holes. Drill four holes over the four marked locations on the wall, keeping in mind that the holes must accommodate wall sinks in addition to the screws.
