c) Equipment intended to operate from either direct- or
alternating-circuit supplies shall bear markings indicating that
the supply may be either direct current or alternating current.
The symbol illustrated in Figure 61.3 may be used for this
marking. The markings shall include the equipment supply-
circuit frequency or supply-circuit frequency-range rating
(cycles per second, cycles/second, hertz, c/s, cps, or Hz).
N/A
61.2.3
If a duty cycle is necessary for proper performance, the time
relationship shall be marked on the product.
N/A
61.2.4
A duty cycle marking may consist of a maximum on and a
minimum off time; or a maximum on time and an on/off ratio.
The time may be indicated in seconds or minutes, or fractions
thereof.
N/A
61.2.5
The polarity of the output leads shall be plainly indicated by:
N/A
a) The words "positive " and "negative ";
N/A
b) The signs "+ " for positive and "− " for negative;
N/A
c) The abbreviations "pos " for positive and "neg " for
negative; or
N/A
d) Color coding of red for positive and black for negative.
N/A
61.2.6
Unless provided with a polarized termination, the polarity of a
direct-current output shall be plainly indicated.

61.2.8
If any point within a terminal box or wiring compartment of a
fixed power unit in which the power unit conductors are
intended to be connected, including such conductors
themselves, attains a temperature of more than 60°C (140°F)
during the normal temperature test, the power unit shall be
marked "For supply connection, use wires suitable for at least
__°C (__°F)," or with an equivalent statement, and the
temperature value shall be in accordance with Table 61.1. This
statement shall be located at or near the point where the supply
connections are to be made, and shall be clearly visible both
during and after installation of the power unit.
N/A
61.2.9

Minimum " or with an equivalent statement if the power unit:
N/A
a) Has a metal enclosure;
N/A
b) Has an ac output rating; and
N/A
c) Is intended to supply a Class1 circuit having an output
rating of 1000 volt-amperes or less.
N/A
Exception No. 1: A power unit is not required to be marked as
specified if provided with a cord and plug for input connections
in which the size of the grounding conductor is not less than
that specified in 61.2.12(a) or 61.2.12(b).
