About this chapter

Read this chapter attentively. It co ntains important info rmation to prev ent pers onal injury while servicing an DB-x20 dis play on- site.

Furthermore, it includes several c autions to prev ent dam age to the DB-x20 tile. Ensure you under stand and follow all the safety

guidelines, safety instructions and warnings mentioned in this chapter before performing any servicing on the DB -x20 dis play. After

this chapter additional “warnings” and “cautions” are give n depending on the servicing procedure. Read and follow these “warnings”

and “cautions” as well.

1.1 Servicing safety instructions

WARNING: Servicingmustbedonebyauthorizedandqualiﬁed technical personnel only, which are thor-

oughly familiar with the product and all of the proper safety checks of this product.

Personal protection

WARNING: E nsure you understand and follow a ll the safety guidelines, safety instructions, warnings and

cautions mentioned in this m anual.

WARNING: Be aw are of suspended loads.

WARNING: Wear a h ard hat to reduce the risk of personal injury.

WARNING: Be careful while w orking w ith heavy loads.

WARNING: Mind your ﬁng ers w hile working with heavy loads.

Safety precautions:

• Follow all s ervicing and safety instructions m entioned in the servicing procedures.

• Unplug the tile AC power c ord 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 c ontains electrostatically sens itive devices (E SD). Take the necessary precautions to prevent the incidence of

component damage c aused by static electricity.

• Do not modify and/or replicate any component. Barco u ses speciﬁc materials and manufacturing processes in order to achieve

part strength. No other parts then Barco parts ar e allowed.

Additional on-site servicing safety precautions:

• Fence off a restricted area of at least 3 meters arou nd the LED-wall using an eye-catching fence and “KEEP O UT ” signs. This

to prevent unauthorized persons coming near the LED-wall during servicing.

• Inspect the complete LED-wall for s ecurity, wear, deformation, corrosion, and any other c ircumstances that m ay effect the load

handling capability of the part.

• Do not modify and/or replicate any component. Barco u ses speciﬁc materials and manufacturing processes in order to achieve

part strength. No other parts than Barco parts are

allowed.

• Both hands must be free for servicing DB-x20 tiles in a LED-wall. Therefore the use of a ladder to access a tile is forbidden.

Only th e use of a scaffold, a buc ket lift or a Z-lift is allowed.

• Do not use the stacker system of the LE D-wall to climb into the DB-x20 display. Always use a scaffold or Z-lift to perform any

servicing or repairing to the display.
