8.2 Troubleshooting UPS Issues
In the event of an issue with the UPS, refer to the following table to determine the cause and solution. If
the fault persists, contact Vertiv™ Technical Support. See
Technical Support on page 63
PROBLEM CAUSE SOLUTION
UPS fails to
start
UPS is short-circuited or
overloaded Ensure UPS is Off. Disconnect all loads and ensure nothing is lodged in output receptacles. Ensure
loads are not defective or shorted internally.
Batteries are not charged
enough or not connected
Check to ensure the internal battery is connected. If it is not, make the connection and try to start the
unit. If the battery is connected, leave the UPS connected to input power for 24 hours to recharge
batteries, then try to start the unit.
Battery
indicator is
illuminated
UPS is not plugged in UPS is operating from battery mode. Ensure UPS is securely plugged into the wall receptacle.
UPS input protection fuse has
blown/opened UPS is operating from battery mode. Save data and close applications. Replace UPS input fuse, then
restart UPS.
Mains power is out of
tolerance UPS is operating from battery mode. Save data and close applications. Ensure mains supply voltage is
within acceptable limits for UPS.
UPS has
reduced
battery
backup time
Batteries are not fully charged Keep UPS plugged in continuously at least 24 hours to recharge batteries.
UPS is overloaded Check load level indicator and reduce the load on the UPS.
Batteries may not be able to
hold a full charge due to age Replace batteries. Contact your local dealer, Vertiv™ representative or Technical Support for
replacement battery kit.
Battery
indicator is
flashing.
Battery source is not available;
continuous horn.
Check battery connections, completely power down and restart UPS.
NOTE: If the battery circuit opens while the UPS is running, it will be detected when the next battery
test is performed.
Bypass
indicator is
flashing.
Because the voltage or
frequency is outside
acceptable limits, the bypass
is disabled.
The AC input powers the PFC input and serves as the bypass source. If the AC is present but the
voltage or frequency exceeds the acceptable range for safe operation with a load, the bypass will be
disabled and this indicator will flash, indicating that the bypass is unavailable.
