Mains power quality should be that of a
typical commercial or institutional
environment. If the user of the Provizio
SEM Scanner Charging Hub requires
continued operation during power mains
interrupts, it is recommended that the
Charging Hub be powered from an
uninterruptible power supply or a battery.
