Mains power quality should be that of a typical commercial
or hospital environment. If the user of the patient
(60% dip in U )for lift requires continued operation during power mains
T T
interruptions, it is recommended that the patient lift be
powered from an un-interruptible power supply or a
(30% dip in U ) for

battery.
U is the a. c. mains voltage prior to application of the

test level.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commercial
or hospital environment.
