Operation (continued)
BATTERY LOW:
This function is to inform users of the remaining power capacity of the
batteries. When batteries reach a low-level condition, the UPS alarm will
beep once every second and the LED on the 25% level will flash.
SHORT CIRCUIT:
When a short occurs in an ON UTILITY MODE, the UPS will shift to
ON BATTERY MODE. If the short persists, the UPS will stop providing
power to loads, alarms will sound continuously and the OVERLOAD LED
will light.
