Power Metering

Four web meters provide voltage and current readings on the
A&B bus. Cumulative killowatt hours are displayed. For non-
PFC corrected loads, a power factor correction value may be
manually enetered on the setup page. Current metering includes
only the switched outlets. Co-location users may elect to use the
unswitched outlets for "house power". To avoid tripped breakers,
take the current drain of the unmetered outlets into account
when operating near the 15A maximum rating.
