Keep 4mm space from the surfaces and sides of PCB. Especially, 8mm space is necessary from the solder surface.
If the space is not enough, the specification of isolation and withstand will not be satisfied.
Keep enough space in the power supply surroundings and the upper area of components for convection cooling.
should be connected to the earth terminal of the equipment. Also the mounting hole are should be connected to the Chassis by metal
spacer. If not, the conducted noise, radiation noise and output noise will increase. Refer to figure below.
