Operator Interface Controls
Operator interface controls are located on the left front door of the main Inverter
Enclosure. These controls include an ON/OFF Switch, 4-line VFD display and keypad
called the Universal Frontpanel Control Unit (UFCU) used to manipulate and view
system operation and status. The keypad is comprised of 20 touch-sensitive keys that
provide a means to navigate through the menus and alter user-changeable settings.
Additionally, there is an AC Disconnect switch handle and DC Disconnect switch handle
on the AC Interface door (left) and the DC Interface door (right) respectively.
