No UPS output
The UPS has not been enabled
Manually Enable
- Make sure that the Remote Function
selector switch is in the Disable position, then press and
hold the UPS Power button until one beep is heard and
release immediately.
Remotely Enable

UPS Operates on battery
although input utility
voltage exists
The system can experience high, low,
or distorted input utility voltage
Reduce the UPS sensitivity by using the 1609 UPS
Management software.
If the problem persists, move or connect the UPS with a
known good quality, utility power source.
Input line utility power
circuit breaker trip
The system can have experienced an
overload
Verify that the circuit breaker is sized properly.
Verify the load that is connected to the output of the UPS.
Ensure that the load does not exceed the output rating of
the UPS.
FAULT LED illuminates
An internal fault has been detected
Refer to the UPS LED Fault Indicators to identify the specific
fault that occurred and possible resolution.
ONLINE LED illuminates, but
no UPS output is available
The UPS output connection cannot be
connected properly
Disable the UPS output and have qualified electrician
troubleshoot the output connection system and make the
necessary corrections.
The battery did not provide
expected runtime
The batteries might be weak or the
lifespan is due
Charge the batteries for 8 hours and retest the runtime.
If the runtime is still less than expected after charging,
replace the batteries even if the Replace Battery LED doesn’t
illuminate.
No communication
between the
UPS and your PC
Wrong cable
Verify cable used.
The connection cable is not firmly
connected
Reconnect the communication cable firmly.
PC Communication Port can have
been used by another process or is
defective
Check if there is other software or service accessing the
Communication Port on your PC, or connect it to a different
communication port.
There is interference on the
connection cable
Lay the cable differently or away from other cables and
reconnect the cable.
