Mechanical Notes:
A Metallic or non-metallic stand-offs (maximum diameter 5.4mm) can be used in all four mounting holes
B The ground pad of the mounting hole near J1, allows system grounding through a metal stand-off to
C The heat sink is grounded, and allows system grounding by mechanical connection to the system
D The supply must be mechanically supported using the PCB mounting holes and may be additionally

supported by the heatsink mounting holes.
It is always advisable to attach the power supply heat sink to another thermal dissipator (such as a
chassis or finned heatsink etc). The resulting decrease in heat sink mounted component temperatures
will improve power supply lifetime.
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” .
