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.
