Safety precautions:
• Follow all servicing and safety instructions mentioned in the servicing procedures.
• Unplug the tile AC power cord from the AC power source and wait about 10 minutes before start any servicing to the tile. This
to allow the capacitors to discharge.
• Some boards contains electrostatically sensitive devices (ESD). Take the necessary precautions to prevent the incidence of
component damage caused by static electricity.
• Do not modify and/or replicate any component. Barco uses speci fi c materials and manufacturing processes in order to achieve
part strength. No other parts then Barco parts are allowed.
Additional on-site servicing safety precautions:
• Fence off a restricted area of at least 3 meters around the LED-wall using an eye-catching fence and “KEEP OUT” signs. This
to prevent unauthorized persons coming near the LED-wall during servicing.
• Inspect the complete LED-wall for security, wear, deformation, corrosion, and any other circumstances that may effect the load
handling capability of the part.
• Both hands must be free for servicing TF-20 tiles in a LED-wall. Therefore the use of a ladder to access a tile is forbidden. Only
the use of a scaffold or a Z-lift is allowed.
• Do not use the stacker system of the LED-wall to climb into the TF-20 display. Always use a scaffold or Z-lift to perform any
servicing or repairing to the display.
• In case of removing an TF-20 LED module out of a tile, ensure the module is secured with a safety cable to the LED-wall
structure.
• Take the necessary precautions to prevent water intrusion inside the TF-20 tile due to weather conditions.
