Troubleshooting the Uninterruptible Power Supply
Table 3-1 lists some possible problems that may occur and solutions:
Table 3-1. Troubleshooting the Uninterruptible Power Supply
Problem and Possible Cause Solution
UPS will not turn on.
• ON button not pushed. Press the ON button once to power on the UPS
and other equipment.
• UPS not connected to AC power
supply. Make sure the power cable from the UPS to the
customer’s input power is securely connected at
both ends.
• UPS input circuit breaker tripped. Reduce the load on the UPS by unplugging
equipment and reset the circuit breaker (on back
of the UPS) until you isolate the device causing the
problem (or the UPS).
• Very low or no utility voltage. Check the AC power supply to the UPS with a
table lamp. If the light is very dim, check the input
voltage.
• Battery not connected properly. Check the battery connections.
UPS will not turn off.
• Internal UPS fault. Do not attempt to use the UPS. Unplug the UPS
and contact your service representative
immediately.
UPS operates on battery although normal line voltage exists.
• UPS’s input circuit breaker tripped. Reduce the load on the UPS by unplugging
equipment and reset the circuit breaker (on back
of the UPS) until you isolate the device causing the
problem (or the UPS).
• Very high, low, or distorted line
voltage.
Note: Inexpensive generators can
distort the voltage.
• Move the UPS to a different outlet on a
different circuit.
• Test the input voltage with the Utility Voltage
display. If acceptable to the load, reduce the
UPS’s sensitivity (refer to the
L180 and L700
Uninterruptible Power Supply Reference
Manual
for more information).
UPS beeps occasionally.
• Normal UPS operation. None. The UPS is protecting the load.
