Mains power quality should be
that of a typical commercial
or hospital environment. If
the user of the Symmetry
IQ 4000 Series requires
continued operation during
power mains interruptions,
it is recommended that
the Symmetry IQ 4000
Series be powered from an
uninterruptible power supply
or a battery.

acteristic 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.
