The wiring differs according to the board to be installed.
• To open a panel, unscrew the 4 screws (BT2045) or the 2 screws (BT2025) (A) on one of the sides
and remove the side. Pull the glass pane out sideways.
Caution : to avoid scratching the glass pane while
pulling it out, carefully avoid any contact between
the pane and the screws or LEDs.
Note : the glass pane of a BT2045 cannot be pulled
out completely.
• To access the electronic board or the power supply unit,
you must unscrew the 2 covers on the front.
•
The scoreboards can be powered by 230V or 110v.
The procedure required to adapt the power supplies
to the input voltage is described on page 24.
