10.1 Accessing Internal Components
Use caution when accessing internal components of the display to remove the LED boards. Follow these
necessary precautions for safe access:
1. Before attempting to remove the LED boards, disconnect the power to the display sign.
a. For an AC-powered display, disconnect the power at the source and power supply cabinet.
b. On solar-powered units, disconnect power at the solar power cabinet.
c. Wait 30 seconds for the system to discharge before handling and removing the LED display
boards.
2. After the power is disconnected, remove the LED boards from the mounting pins.
3. Be very careful not to touch or move the LEDs. They have been factory aligned for optimal visibility.
4. Disconnect all power before reinstalling the LED boards back onto the mounting pins.
Do not attempt to access internal components without first disconnecting the power
supply.

Mating connectors improperly may cause damage.
