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” .
