An uninsulated live part that can cause electric shock shall be
located or enclosed so that protection against unintentional
contact is provided.

Protection of Service Personnel
N/A
9.1
General
N/A
9.1.1
These requirements apply to live parts used in circuits involving
a risk of electric shock.
N/A
9.1.2
Live parts shall be so arranged and covers so located as to
reduce the risk of electric shock when covers are being
removed and replaced.
No cover
N/A
9.1.3
Consideration shall be given to a construction in which live
parts are recessed at least 1/8 inch (3.2 mm) from the plane of
the front of the fixed portion of the enclosure, and to an
equivalent construction incorporating projections or guards.
N/A
9.1.4
An uninsulated live part involving a risk of electric shock and a
moving part that involves a risk of injury to persons shall be
located, guarded, or enclosed to reduce the likelihood of
unintentional contact with such part by persons while changing
a lamp or fuse, lubricating a motor, adjusting a control, or
performing other like operations, including those performed
only at the time of installation or during servicing procedures.
N/A
9.1.5
A live heat sink for a solid-state component, a live relay frame,
a live part that can be mistaken for dead metal, and the like
shall comply with the requirements in 9.2.2 and 9.3.1. Such a
part shall also either be guarded to prevent contact by persons
or be marked in accordance with 61.1.2.
No such construction
N/A
Exception: This requirement does not apply to a heat sink
mounted on a printed wiring board.
N/A
9.1.6
A means such as a bleeder resistor shall be provided to drain
the charge stored in a capacitor to the extent that the potential,
V, measured between the terminals of the capacitor 1 minute
after the capacitor has been disconnected from its source of
energy is less than 50 volts, and the energy stored, J, is less
than 20 joules as determined by the following relation, in which
C is in microfarads: J = 5 x 10-7 CV2
N/A
Exception: The requirement does not apply if a tool is
necessary to remove a panel to reach the capacitor and the
power unit is marked to warn service personnel as specified
in 61.1.15.
N/A
9.2
Mechanical servicing
N/A
9.2.1
The requirements in 9.2.2 are intended to provide a reasonable
degree of protection to the service personnel performing
mechanical functions on energized equipment. Such functions
do not in themselves require exposure to live parts involving a
risk of electric shock or to moving parts that involve a risk of
injury to persons, but it is usually necessary to perform them
with the equipment energized.
