Guidance and manufacturer’s declaration – electromagnetic immunity
The imagiQ2 is intended for use in the electromagnetic environment specified below. The customer or the user of the imagiQ2 should
assure that it is used in such an environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment -
guidance
Electrostatic discharge (ESD)
IEC 61000-4-2 +/- 6 kV contact
+/- 8 kV air +/- 6 kV contact
+/- 8 kV air Floors should be wood, concrete
or ceramic tile.
If floors are covered with synt-
hetic material,
the relative humidity should be
at least 30 %.
Electrical fast transient / Burst
IEC 61000-4-4 +/- 2 kV for power supply lines
+/- 1 kV for input/output lines +/- 2 kV for power supply lines
n/a. for input/output lines Mains power quality should be
that of a typical commercial or
hospital environment.
Surge
IEC 61000-4-5 +/- 1 kV differential mode
+/- 2 kV common mode +/- 1 kV differential mode

Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the [Equipment or System]
requires continued operation
during power mains interrup-
tions, it is recommended that
the [Equipment or System] be
powered from an uninterruptible
power supply or battery.
Power frequency (50/60 Hz)
magnetic field
IEC 61000-4-8 3 A/m 3 A/m Power frequency magnetic fields
should be at levels characte-
ristic 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.
Essential performance according to EN 60 601-2-46: Essential performance of the imagiQ2 table is the Trendelenburg function. The function
can be activated by the use of the hand control and can manually be achieved as an emergency function in cases of power failure.
No permanent degradation or loss of function or operator settings which are not recoverable shall be observed at any immunity test level.
No inappropriate movement shall occur at all immunity test levels.
At all immunity test levels the ME EQUIPMENT shall maintain essential performance within the
specification limits.
At all immunity test levels the temporary degradation or loss of function or performance is
acceptable.
Within 10 s or after operator intervention without requiring the use of a tool, the
ME EQUIPMENT shall resume normal operation in the previous operating mode, without loss of
any operator settings or stored data, and shall continue to perform its intended function.
Compliance criteria.
Under the test conditions specified in 36.202 in EN 60 601-1-2 (2007), the equipment shall be able to provide the essential performance
and remain safe. The following degradations associated with essential performance and basic safety shall not be allowed:
- Component failure Not allowed
- Changes in programmable parameters Not allowed
- Reset to factory defaults Not allowed
- False alarms Not allowed
- Cessation or interruption of any intended operation, even if accompanied by
an alarm Allowed only during voltage interruption >95% 5s
- Initiation of any unintended operation, even if accompanied by an alarm Not allowed
- Error of a displayed numerical value sufficiently large to affect diagnosis or
treatment. Not allowed
The equipment may exhibit degradation of performance that does not affect essential performance or safety.
