Mount the unit to at least two points on the installation location. Please note the following when mounting on wall or ceiling • NEC recommends mounting interfaces that comply with UL1678 standard in North America. • NEC strongly recommends using size M6 screws (8-10 mm + thickness of bracket and washers in Unit No gap No thread 2.0 mm Mounting Bracket Washers length). If using screws longer than 8-10 mm, under ϕ 8.0 mm Screw check the depth of the 8-10 mm Thickness of hole. (Recommended Fasten Force: 470 - 635 bracket and washers N•cm). Bracket hole should be under ϕ 8.0 mm. • Prior to mounting, inspect the installation location to ensure that it is strong enough to support the weight of the unit so that the unit will be safe from harm. • For detailed information, refer to the instructions included with the mounting equipment. • Make sure that there is no gap between the monitor and the bracket. • When used in a video wall configuration for a longer time, slight expansion of the monitors may happen due to temperature changes. Due to this it is recommended that over one millimeter gap is kept between adjacent monitor edges. • When installing, do not apply pressure to the screen or excessive force to any part of the monitor by pushing or leaning on it. This may cause the monitor to become distorted or damaged. To prevent the LCD monitor from falling off from the wall or ceiling, NEC strongly recommends using a safety wire. Please install LCD monitor in a spot of the wall or ceiling strong enough to support the monitor. Prepare the LCD monitor using mounting accessories such as hook, eyebolt or mounting parts and then secure the LCD monitor with a wire. The safety wire must not be tight. CAUTION: Do not attempt to hang the monitor using an installation safety wire. The monitor must be properly installed. Please make sure the mounting accessories are strong enough to support the LCD monitor before mounting it. Mounting location • The ceiling and wall must be strong enough to support the monitor and mounting accessories. • DO NOT install in locations where a door or gate can hit the unit. • DO NOT install in areas where the unit will be subjected to strong vibrations and dust. • DO NOT install the monitor next to a location where the main power supply is fed into the building. • DO NOT install the monitor in a location where people can easily grab and hang onto the unit or the mounting equipment. • Allow for adequate ventilation or provide air conditioning around the monitor, so that heat can properly dissipate away from the monitor and from the mounting equipment. Mounting on ceilings • Ensure that the ceiling is sturdy enough to support the weight of the unit and the mounting equipment over time, against earthquakes, unexpected vibrations, and other external forces. • Be sure the unit is mounted to a solid structure within the ceiling, such as a support beam. Secure the monitor using bolts, spring lock washers, washer and nut. • DO NOT mount to areas that have no supporting internal structure. DO NOT use wood screws or anchor screws for mounting. DO NOT mount the unit to ceiling or to hanging fixtures. Maintenance • Periodically check for loose screws, gaps, distortions, or other problems that may occur with the mounting equipment. If a problem is detected, please refer to qualified personnel for service. • Regularly check the mounting location for signs of damage or weakness that may occur over time. English-6
