INVERTER ON WARNINGS
When the inverter is ON, the LCD Display may show any one of the following warnings:
Condition LCD Display Message
UPS Output Overload OVERLOAD 110%
UPS Charger Failure CHARGER FAILURE
Abnormal Input Frequency FREQUENCY ERROR
Abnormal Input Phase PHASE ABNORMAL!
Battery is Depleting* ON BATTERY
Battery Charge is Nearly Depleted* BATTERY LOW
* Since the UPS System can only provide battery backup only for as long as the
batteries remain charged, these warnings should be acted on immediately.
Operation (Special Conditions)
OPERATION ON BYPASS—VOLTAGE OUT OF RANGE
While in Bypass Mode, the UPS monitors the input voltage, which on Bypass equals the output voltage. If the output voltage passes out of
an acceptable range (between 15% higher and 20% lower than nominal), the UPS displays the condition on its LCD and stops supplying
output power to its load. If power levels return to an acceptable level, the UPS resumes supplying power to the load, and its LCD reports
that output voltage was too high or too low at one time, but has returned to nominal.
