Wall Mounting Info Appendix C: Wall Mounting Guide The computer may be mounted on a wall for display, however in order to avoid personal injury or damage to the computer make note of the standards, warnings and precautions listed in this chapter: The system meets VESA (FDMI) Standard (100mm * 100mm), however before attaching any display bracket it is nec- essary to remove the stand.
Wall Mounting Info Removing the Stand Figure 1 1. Turn off the computer and disconnect all cables and peripherals. Stand Removal 2. Carefully place the computer flat with the LCD facing down (make sure you cover the LCD to avoid scratches) so that you may access the rear cover.
Wall Mounting Info Mounting Systems This computer complies to the VESA FDMI (Flat Display Mounting Interface) 100mm * 100mm standard. Make sure that any mounting system you want to use meets the same standard. It is imperative that you consult appropriate professional installers (i.e. qualified engineering, construction or architec- tural personnel) to install, move or service any mounting system.
Wall Mounting Info General Guidelines for Wall Mounting • Only use professional installers to install, move or service any mounting system. • The system must only be mounted on a wall which can support the whole system’s weight (including the weight of any arm or bracket).
Wall Mounting Info Mounted System Example The following pictures show some examples of how a system can be mounted on to a wall. These pictures are intended for guideline purposes only, and are not specific instructions. Professional installers will determine the exact installation procedure for your specific bracket and mounting conditions.
Page 104
Wall Mounting Info 3. The display can now be mounted by lowering the display bracket (in this example) over the wall bracket and attaching the screws. Note that this procedure usually requires two people, as one person will need to hold the computer while the other inserts and tightens the screws.
