Bypass AC source
Source supplying the bypass line. The equipment can be transferred to
the bypass line if an overload occurs on the UPS output, for maintenance
or in the event of a malfunction.
Frequency converter
Operating mode used to convert the AC-power frequency between the
UPS input and output (50Hz -> 60Hz or 60Hz -> 50Hz).
Low-battery warning
This is a battery-voltage level indicating that battery power is low and
that the user must take action to prevent the imminent break in the
supply of power to the load.
Backup time
Time during which the load can be supplied by the UPS operating on
battery power.
Load
Devices or equipment connected to the UPS output.
HE mode
Operating mode by which the load is supplied directly by the AC source
if it is within the tolerances defined by the user. This mode reduces the
consumption of electrical power
Manual bypass
Rotary switch controlled by the user, used to connect the loads directly
to the AC source. Transfer of the load to the manual bypass enables UPS
maintenance without interrupting the supply of power to the connected
loads.
Normal (double
conversion) mode
The normal UPS operating mode in which the AC source supplies the
UPS which in turn supplies the connected loads (after electronic double
conversion).
Normal AC source
Normal source of power for the UPS.
Relay contacts
Contacts supplying information to the user in the form of signals.
UPS
Uninterruptible Power Supply.
