GUIDANCE AND MANUFACTURER'S DECLARATION: ELECTROMAGNETIC
IMMUNITY
SERFAS Energy Systemis intended for use in the electromagnetic environment specified below. The customer or
the user of SERFAS Energy Systemshould ensure that it is used in such an environment.
IMMUNITY TEST
IEC 60601 TEST
LEVEL
COMPLIANCE
LEVEL
ELECTRO-
MAGNETIC
ENVIRONMENT:
GUIDANCE
Electrostatic Discharge
(ESD)
IEC61000-4-2
±6kV contact
±8kV air
±2,4,6kV contact
±2,4,8kV air
Floors should be wood,
concrete, or ceramic tile.
If floors are covered with
synthetic material, the
relative humidity should
be at least 30%.
Electrical fast transient/
burst
IEC61000-4-4
±2kV for power
supply lines
±1kV for input/
output lines
±2kV for power
supply lines
±1kV for input/output
lines
Mains power quality
should be that of a typical
commercial or hospital
environment.
Surge
IEC61000-4-5
±1kV differential

±2kV common mode
±0.5, 1kV differential
mode
±1, 2kV common

Mains power quality
should be that of a typical
commercial or hospital
environment.
Voltage dips, short
interruptions and voltage
variations on power supply
input lines
IEC61000-4-11
<5% Ut (>95% dip in
Ut) for 0.5 cycle
40% Ut (60% dip in
Ut) for 5 cycles
70% Ut (30% dip in
Ut) for 25 cycles
<5% Ut (>95% dip in
Ut) for 5 sec.
<5% Ut (>95% dip in
Ut) for 0.5 cycle
40% Ut (60% dip in
Ut) for 5 cycles
70% Ut (30% dip in
Ut) for 25 cycles
<5% Ut (>95% dip in
Ut) for 5 sec.
Mains power quality
should be that of a typical
commercial or hospital
environment. If the user
of SERFAS Energy
Systemrequires
continued operation
during power mains
interruptions, it is
recommended that
SERFAS Energy
Systembe powered from
an uninterruptible power
supply or a battery.
Power frequency (50/60Hz)
magnetic field
IEC 61000-4-8
3 A/m N/A
Power-frequency
magnetic fields should be
at levels characteristic of
a typical location in a
typical commercial or
hospital environment.
NOTE: Ut is the a.c. mains voltage prior to application of the test level.
