Operator Interface Controls

Operator interface controls are located on the left front door of the main inverter

enclosure. These controls include an O

N/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.

WARNING: Risk of electric shock, explosion and arc flash

Turning the ON/OFF switch to the OFF postion does not remove all hazardous

voltages from inside the inverter. Before attempting to service the Xantrex GT250,

follow the procedure for “Lock-out and Tag-out (De-energize/Isolation

Procedure)” on page xiii.
