8.2 Glossary
Backup time
Time that the connected equipments can operate on battery power.
Bypass AC source
Source supplying the bypass line. The equipments can be transferred to the bypass line if
an overload occurs on the UPS output, for maintenance or in the event of a malfunction.
ECO mode
Operating mode by which the equipments are supplied directly by the AC source if it is
within the tolerances defined by the user. This mode reduces the consumption of electrical
power.
Equipments
Devices or systems connected to the UPS output.
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).
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.
Manual bypass
Rotary switch controlled by the user, used to connect the equipments directly to the AC
source. Transfer of the equipments to the manual bypass enables UPS maintenance
without interrupting the supply of power to the connected equipments.
Normal AC source
Normal source of power for the UPS.
Normal (double
conversion) mode
The normal UPS operating mode in which the AC source supplies the UPS which in turn
supplies the connected equipments (after electronic double conversion).
Personalisation
It is possible to modify certain UPS parameters set in the factory. Certain UPS functions
can also be modified by the
EATON
power management products to better suit user
needs.
Programmable
outlets
These outlets can be automatically shut down during operation on battery power
(shutdown time delays can be programmed with the
EATON
power management
products).
The UPS has two sets of two programmable outlets.
Relay contacts
Contacts supplying information to the user in forme of signals.
UPS
Uninterruptible Power System.
