OVERLOAD
SITE FAULT
OVERTEMP
BATTERY
SELF TEST
Power requirements exceed UPS
capacity. If overload is greater
than 105%, the alarm beeps
every second and the UPS may
switch to Bypass mode.
Your UPS continues to operate.
Reduce load.
OVERLOAD
The UPS switched to Bypass
mode because the overload
increased (above 105%). The
alarm beeps.
Reduce load.
If the Overload indicator remains lit, reset
the UPS by pressing the Output
On
button until the alarm beeps.
You may need to obtain a larger capacity
UPS.
SITE FAULT
Building wiring is out of
specification. The UPS checks
the utility power source during
startup for reversed neutral and
line conductors. The alarm
beeps.
Have site wiring tested. Repair as required.
The utility line voltage and
frequency are out of
specification.
The inverter remains online, deriving
power from the utility until it is no longer
acceptable.
Check the unit configuration.
Refer to the product specifications (see
page 55).
