In the display, the signal surge suppression board is an inline device used to filter the current
loop data line. It suppresses surges down to a low voltage to protect the display’s controller.

The surge board is pre-wired before the display is shipped.
Note: The surge suppressor must be firmly connected to the driver enclosure, and the display
must be properly grounded in order to be effective.
