:
Electrostatic Sensitive Device (ESD). To avoid equipment damage from electrostatic discharge,
use static control precautions in servicing this equipment. Field service or maintenance personnel should
be properly grounded before servicing. Wear an ESD wristlet when servicing this equipment. The use of
antistatic gloves is recommended.
Never swap a LED module or LED driver or controller from an ILite tile, because measurement results of the
LED module are stored on the LED driver and controller. So, these boards are matched to each other during
the factory measurement process. Even a swap among the LED modules or LED drivers of the same tile
is not allowed. Neglecting this will result in poor video images displayed on the LED wall. The swapped
LED modules or LED drivers will become visible as quadrants with different light output. Always return the
complete ILite tile to factory for repair and re-measurement in case of a malfunction controller or one or more
malfunction LED modules or LED drivers.
Ensure that all LED modules are installed before installing the LED drivers.
Necessary tools
• Torx T20.
• 7 mm nut driver.
• Compressed air.
How to install the LED driver upon the module base plate ?
1. Gently place the LED driver (G) in its original position on the module base plate (F).
Tip: Ensure there is no dust in the sockets of the board to board connectors. Use compressed air to blow out the dust.
Caution: Be careful with the board to board connectors between the LED driver and the LED modules underneath.
