7.8.4.1 Instructions to power up the display unit
Figure 74: Power connections
The display unit can be powered with two different power sources. Both power sources
can supply power to the display unit simultaneously. The power supply of the display unit
will decide which supply of power is preferred to deliver optimal performance. Priority is
given to the 100-240Vac power input when both power sources are within the operational
tolerances. The display unit communicates the status of the power supply via the
indicator lights. Please check the section that deals with the indicator lights in the chapter
“Full functionality description” for more information.
CAUTION
:
Before connecting the display unit to mains, check if the power source voltage corresponds to the
mains voltage marked on the identification label on the display.
NOTE
:
Power voltage specifications are available in the Technical specifications section.
To power-up the display unit:
• Place the display unit up-right (on the Barco stand) or mount the display unit safely
into a rack.
• Connect the power cord of the appropriate power supply to the power connector at
the back of the display unit.
• Power up the display unit by switching the power switch on.
• The display unit will start-up (you should hear the ventilators spin) and perform
some checks before displaying an image on the screen. The status of the start-up
checks can be followed by the flashing of the indicator lights. The start-up can take
