functional ground is electrically connected to the switching ground and to the
metal housing of the device.
For the ground wire, use a copper wire with a minimum cross section of
4 mm

(for North America: AWG 11 to AWG 9) (including any
terminal sleeve used), and implement the grounding of the device via the
screw connector.
Clamp the ground wire between the two rectangular fastening plates - as
shown in the figure below - and fasten the screw.
Make sure that the ground wire is not in direct contact with the aluminum
