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 MGE UPS SYSTEMS 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 MGE UPS SYSTEMS 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.
