Beginner here. I am working on a project using a Sure amplifier and noticed there is a ground label on one of the holes used for mounting. Do I need to do anything special for this? The link below shows the pcb and the bottom right mount hole with the ground symbol.

I'm assuming that this is the 2 x 15W amplifier. If so, the Notice section details the proper use of the GND terminal:

GND should be connected to GND or the housing of your instrument.
