SECTION 9 GUIDANCE AND MANUFACTURER’S DECLARATION
– ELECTROMAGNETIC IMMUNITY
(for all Medical Equipment and Medical Equipment Systems that are not Life-Supporting)
The ALLY UPS is intended for use in the electromagnetic environment specified below. The customer or the user
of the ALLY UPS should assure that it is used in such an environment.
ELECTROMAGNETIC
IMMUNITY TEST
IEC 60601 TEST LEVEL COMPLIANCE LEVEL ENVIRONMENT GUIDANCE
Portable and mobile RF
communications equipment should
be used no closer to any part of the
Ally UPS, including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.

transmitter manufacturer and
d
is
the recommended separation

Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance
level in each frequency range.
b
Interference may occur in the
vicinity of equipment marked with
the following symbol:
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
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast, and TV 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 Ally UPS is used exceeds the applicable
RF compliance level above, the ALLY UPS should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the ALLY UPS.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
