Direct current, or voltage.
The LCD display on the front panel of inverter system.
A ground circuit that has contact with the earth.
Operating mode by which the load is supplied directly by the AC source if it is within the
tolerances defined by the user. This mode reduces the consumption of electrical power.
Refers to an installation electrician qualified to install high-energy electrical components in
accordance with national and local codes and regulations. Not necessarily qualified to main-
tain or repair electrical or electronic equipment. Compare to Technician.
Emergency Power Off. Used to switch all UPS/critical power OFF. For emergency
power shutdown only.
The change in frequency per unit of time. Given in term of Hz per second (Hz/sec.).
