Basic Operation

Power Sensitivity Adjustment: This dial is normally set fully counter-clockwise,
which enables the UPS to provide maximum protection against waveform distortions
in its AC input. When such distortion occurs, the UPS will normally switch to
providing sine wave power from its battery reserves for as long as the
distortion is present. In areas with poor utility power or where the UPS's input
power comes from a backup generator, chronic waveform distortion could
cause the UPS to switch to battery too frequently, draining its battery reserves.
You may be able to reduce how often your UPS switches to battery due to
moderate waveform distortion by experimenting with different settings for this
dial. As the dial is turned clockwise, the UPS becomes more tolerant of
variations in its input power's AC waveform. NOTE: The further the dial is
adjusted clockwise, the greater the degree of waveform distortion the UPS will
allow to pass to connected equipment. When experimenting with different
settings for this dial, operate connected equipment in a safe test mode so that the
effect on the equipment of any waveform distortions in the UPS's output can be
evaluated without disrupting critical operations.
Input Breaker: Protect your electrical circuit from overcurrent draw from the
UPS load. If these breakers trip, remove some of the load, then reset them by
pressing the breaker(s) in.
