TECHNICAL SPECIFICATIONS
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) ME 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 SYSTEMS. The IMMUNITY TEST
LEVELS are applied to the a.c. power input of the
converter.
g) Applicable only to PIEZOSURGERY® GP connected to
single-phase a.c. mains.
h) E.g. 10/12 means 10 periods at 50 Hz or 12 periods
at 60 Hz.
i) ME 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). PIEZOSURGERY® GP
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.
j) ME EQUIPMENT and ME SYSTEMS that does 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 CLASS II PIEZOSURGERY® GP.
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 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. ME 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.
