Main power quality should be that of a typical commercial and/or
hospital environment. If the user of the VPULSE requires continued
operation during power main interruptions, it is recommended that the
VPULSE be powered from an uninterruptible power supply or a battery.
If improper operation occurs, it may be necessary to position the
VPULSE further from sources of power frequency magnetic fields or to
install magnetic shielding. The power frequency magnetic field should
be measured in the intended installation location to ensure that it is
sufficiently low.
