(while in back-up mode)
3.02 “OFF” Button
Pressing this button turns OFF the UPS and its connected loads.
3.03 “SELECT” Button
Depressing and holding the select button cycles through various LCD display modes. Modes include:
Input Voltage, Output Voltage, Input Frequency, Output Frequency and the Internal Temperature of
the UPS.
3.04 LINE:
Indicates normal operation from AC line.
3.05 BYPASS:
Indicates the UPS is in bypass mode due to a fault or manual bypass 'force' selection (See section 5).
