a)
The test may be performed at any one power input voltage within the
ME EQUIPMENT
or
ME SYSTEM RATED
voltage range. If the
ME EQUIPMENT
or
ME SYSTEM
is tested at one power input voltage, it is not necessary to
re-test at additional voltages.
b)
All
ME EQUIPMENT
and
ME SYSTEM
cables are attached during the test.
c)
Calibration for current injection clamps shall be performed in a 150
Ω
system.
d)
If the frequency stepping skips over an ISM or amateur band, as applicable, an additional test frequency
shall be used in the ISM or amateur radio band. This applies to each ISM and amateur radio band within the
specified frequency range.
e)
Testing may be performed at other modulation frequencies identified by the
RISK MANAGEMENT PROCESS
.
f)
M
E EQUIPMENT
and
ME SYSTEMS
with a d.c. power input intended for use with a.c.-to-d.c. converters shall be
tested using a converter that meets the specifications of the
MANUFACTURER
of the
ME EQUIPMENT
or
ME SYSTEM
. The
IMMUNITY TEST LEVELS
are applied to the a.c. power input of the converter.
g)
Applicable only to
ME EQUIPMENT
and
ME SYSTEMS
connected to single-phase a.c. mains.

M
E EQUIPMENT
and
ME SYSTEMS
with
RATED
input current greater than 16 A / phase shall be interrupted once
for 250/300 cycles at any angle and at all phases at the same time (if applicable). M
E EQUIPMENT
and
ME
SYSTEMS
with battery backup shall resume line power operation after the test. For
ME EQUIPMENT
and
ME SYSTEMS
with
RATED
input current not exceeding 16 A, all phases shall be interrupted simultaneously.
