Ultium Motion Hardware User Manual
Guidance and manufacturer's declaration – electromagnetic immunity
The Ultium System is intended for use in electromagnetic environment specified below. The customer or the user of the
Ultium System should assure that it is used in such an environment.
Immunity Test
IEC 60601 test level
Conducted RF
3 Vrms
IEC 61000-4-6
150 kHz to 80 MHz
(Charging System)
6 Vrms
150 kHz to 80 MHz
in ISM and amateur radio
bands
Radiated RF
6 V/m
IEC 61000-4-3
80 MHz to 2.7 GHz
NOTE 1
At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
a
The ISM (industrial, scientific and medical) bands between 150 kHz 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.
b
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range 80
MHz to 2.7 GHz are intended to decrease the likelihood that mobile/portable communications equipment could
cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 has
been incorporated into the formulae used in calculating the recommended separation distance for transmitters in
these frequency ranges.
c
Field strengths from fixed transmitter, such as base stations for radio (cellular/cordless) telephones and land mobile
radios, amateur radio, AM and FM radio broadcast cannot be predicted theoretically with accuracy. To assess the
electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If
the measured field strength in the location in which the Ultium Motion Sensor & Receiver s used exceeds the
applicable RF compliance level above, the Ultium Motion Sensor & Receiver should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or
relocating the Ultium Motion Sensor & Receiver.

Electromagnetic environment -
guidance
Portable and mobile RF communications
equipment should be used no closer to
any part of the Ultium System, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2,5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters,
as determined by an electromagnetic site
a
survey,
should be less than the
compliance level in each frequency

range.
Interference may occur in the vicinity of
equipment marked with the following
