3. DISPLAYS AND ALARMS
1. Load level and battery capacity is represented by 5 LEDs on the upper half of control panel (the 6th LED means FAULT).
(A). When the UPS is in the On-Line mode, the 5 LEDs represent load level. They denote 0%~35%, 35%~55%, 55%~75%,
75%~95% and 95%~105% (from buttom to top) of maximum load capacity. If the load amount reaches 105%~130%, the UPS
is in overload such that the 6 LEDs would illuminate simultaneously. The UPS will then switch to BYPASS mode10 seconds
later. In addition, if the load is over 130%, the UPS will switch to BYPASS immediately.

(B). During an AC line power failure, these 5 LEDs represent the remaining battery capacity. The LED’s will extinguish by the
sequence from bottom to top as the battery voltage level decreases.
