j)
M
E EQUIPMENT
and
ME SYSTEMS
that do not have a surge protection device in the primary power circuit may
be tested only at
±
2 kV line(s) to earth and
±
1 kV line(s) to line(s).
k)
Not applicable to C
LASS II ME EQUIPMENT
and
ME SYSTEMS
.
l)
Direct coupling shall be used.
m)
r.m.s., before modulation is applied.
n)
The ISM (industrial, scientific and medical) bands between 0,15 MHz and 80 MHz are 6,765 MHz to
6,795 MHz; 13,553 MHz to 13,567 MHz; 26,957 MHz to 27,283 MHz; and 40,66 MHz to 40,70 MHz. The
amateur radio bands between 0,15 MHz and 80 MHz are 1,8 MHz to 2,0 MHz, 3,5 MHz to 4,0 MHz, 5,3 MHz
to 5,4 MHz, 7 MHz to 7,3 MHz, 10,1 MHz to 10,15 MHz, 14 MHz to 14,2 MHz, 18,07 MHz to 18,17 MHz,
21,0 MHz to 21,4 MHz, 24,89 MHz to 24,99 MHz, 28,0 MHz to 29,7 MHz and 50,0 MHz to 54,0 MHz.
o)
Applicable to
ME EQUIPMENT
and
ME SYSTEMS
with
RATED
input current less than or equal to 16 A / phase and
ME EQUIPMENT
and
ME SYSTEMS
with
RATED
input current greater than 16 A / phase.
p)
Applicable to
ME EQUIPMENT
and
ME SYSTEMS
with
RATED
input current less than or equal to 16 A / phase.
q)
At some phase angles, applying this test to
ME EQUIPMENT
with transformer mains power input might cause
an overcurrent protection device to open. This can occur due to magnetic flux saturation of the transformer
core after the voltage dip. If this occurs, the
ME EQUIPMENT
or
ME SYSTEM
shall provide
BASIC SAFETY
during
and after the test.
r)
For
ME EQUIPMENT
and
ME SYSTEMS
that have multiple voltage settings or auto ranging voltage capability, the
test shall be performed at the minimum and maximum
RATED
input voltage. M
E EQUIPMENT
and
ME SYSTEMS
with a
RATED
input voltage range of less than 25 % of the highest
RATED
input voltage shall be tested at one
RATED
input voltage within the range. See Table 1 Note c) for examples calculations.
