type of battery your APS will be connected to and the voltage points at which your APS
will switch to battery power. See “Configuration”, p. 5 to select the optimum settings for
these switches.

3.. ““L
LIIN
NE
E””:: This green light will turn continuously ON whenever connected equipment is
receiving utility-supplied AC power and your APS is set to “AUTO/REMOTE”, meaning that
it will automatically switch to battery power if AC power becomes unavailable. It will
flash intermittently when connected equipment is receiving utility power and your APS’s
Operating Mode Switch is set to “CHARGE ONLY” to indicate that the APS’s inverter is
OFF and that the APS will not supply power from its batteries.

4.. ““IIN

receiving battery-supplied AC power. It will flash if the APS does not detect the minimum
load necessary to activate the inverter.

5.. ““L

D””:: When your UPS is receiving utility-supplied AC power, this red light will turn
continuously ON when the APS’s load is between 80% and 110% of capacity, to alert you
that the inverter might not be able to support the load.The light will flash intermittently
after the APS’s inverter shuts down due to a severe overload or overheating. If this hap-
pens, turn Operating Mode Switch OFF. Remove the overload and let the unit cool.You
may then turn the APS ON after it cools.
