Bypass AC input Bypass line from the AC-power source, controlled by the UPS, used to directly
supply the load if an overload or a malfunction occurs on the UPS.
Backup time Time during which the load can be supplied by the UPS operating on battery power.
Battery test Internal UPS test to check battery status.
Equipments Devices connected to the UPS output.
Excessive discharge Battery discharge beyond the permissible limit, resulting in irreversible damage to the
battery.
FlexPDU Module with UPS outlets for installation in a bay. There are different modules with dif-
ferent types of outlets.
Frequency converter Operating mode used to convert the AC-power frequency between the UPS input and
output (50 Hz -> 60 Hz or 60 Hz -> 50 Hz).
HotSwap MBP UPS manual-bypass module for maintenance. There are different modules with differ-
ent types of outlets.
Low-battery warning This is a battery-voltage level indicating that battery power is low and that the user
must take action in light of the imminent break in the supply of power to the load.
Normal AC input The AC-power line supplying the UPS under normal conditions.
Percent load Ratio of the power effectively drawn by the load to the maximum output of the UPS.
Personalization It is possible to modify certain UPS parameters set in the factory. Certain UPS functions
can also be modified by the Personal Solution-Pac software to better suit user needs.
Programmable outlets These outlets can be automatically shut down during operation on battery power (shut-
down time delays can be programmed with the Personal Solution Pac software). The
UPS has two sets of two and one programmable outlets.
Start on battery power The devices connected to the UPS can be started even when AC power is not available.
The UPS operates only on battery power.
UPS Uninterruptible Power Supply.
