Mechanical Notes
A Metallic or non-metallic stand-offs (maximum diameter 5.4mm) can be
used in all four mounting holes without effecting safety approval.
B The ground pad of the mounting hole near J1, allows system grounding
through a metal stand-off to the system chassis.
C The heat sink is grounded, and allows system grounding by mechanical
connection to the system chassis.
D The supply must be mechanically supported using the PCB mounting
holes and may be additionally supported by the heatsink mounting
holes.
E It is always advisable to attach the power supply heat sink to another
thermaldissipator(suchasachassisornnedheatsinketc).The
resulting decrease in heat sink mounted component temperatures will
improve power supply lifetime.
F A standard L-bracket and cover is available for mounting which contains
all screws, connectors and necessary mounting hardware. The kit is
available, order part number “NFS110CJ” .
