Battery replacement is a safe procedure that is
isolated from electrical hazards. You can leave the
UPS and attached loads powered “ON” during the
procedure. If the unit is “ON,” the audible alarm will
sound when the battery is disconnected and the
yellow and red LEDs will blink.
NOTE:
The UPS cannot protect against power
outages while the batteries are disconnected.
