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 finned 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”.
