Battery
v Bypass
v
Standby
Note: If the UPS is unable to continue operating normally, it might attempt to save
data and follow an orderly shutdown sequence. However, some unrecoverable
failures and overload conditions cause the UPS to transfer to Fault mode without
saving data, and turn off immediately to protect the UPS and the load from damage.
Normal mode
The UPS supplies the load power from utility power. The UPS monitors and
charges the batteries as needed and provides filtered power protection to your
equipment.
Battery mode
The UPS supplies the load power from battery. The status text flashes and the UPS
beeps every 5 seconds. When the utility power returns, the UPS transfers to
Normal mode operation while the battery recharges.
Bypass mode
The UPS supplies the load power through an automatic internal bypass. Battery
mode is not available. The UPS transfers to Bypass mode when you activate
Bypass mode through the front panel (manual bypass) or when the UPS detects a
condition requiring bypass (automatic bypass).
Standby mode
When the UPS is turned off and remains connected to the power source, the UPS
is in Standby mode. The UPS is not supporting the load but is ready to assume the
load on command.
