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” .
