Indicator Lights
4.“LINE” (All models): This green light will turn continuously ON whenever connected equipment is receiving
5.“INV”
6.“LOAD” (All models): This red light will turn continuously ON when the APS’s load is between 80% and 110% of capacity. The light will flash intermittently when the APS’s inverter shuts down due to a severe overload or overheating. If this happens, turn Operating Mode Switch OFF. Remove the overload and let the unit cool. You may then turn the APS ON after it cools.
7.“CUT/BOOST” (VRI models only): These lights will turn ON whenever your APS is automatically correcting high (CUT) or low (BOOST) AC line voltage. This is a normal, automatic operation of your APS that does not drain battery power, and no action is required on your part.
8.“BATTERY HI/MED/LO” (All models): These three lights will turn ON in several sequences to show the approximate charge level and voltage of your connected battery bank and alert you to several fault conditions:
