The rate at which the UPS frequency is synchronized with that
of the AC-power source. Two possible cases:
1. The installation comprises a single UPS. The frequency-regulation rate
is set to "Standard".
2. The installation comprises two UPSs connected in series. The AC-power
source supplies power to the first UPS which in turn supplies the second UPS.
The connected equipment is supplied by the second UPS.
The frequency regulation rate of the first UPS must be set to "Standard",
the frequency regulation rate of the second UPS must be set to "Redundancy".
Connection module (with manual bypass) offering a socket for connection
to the AC-power source and outlets or a terminal block for connection
to the equipment.
Connection module (with manual bypass) offering terminal blocks
for connection to the AC-power source and the equipment.
Rotary switch controlled by the user, used to connect the equipment directly
to the AC-power source. Transfer of the load to the manual bypass enables
UPS maintenance or replacement, without interrupting the supply of power
to the connected equipment.
The normal UPS operating mode, by which the AC-power source supplies
the UPS, which in turn, following double conversion of the AC power,
supplies the connected equipment.
Ratio between the power drawn by the connected equipment and the total
power that the UPS can supply.
A number of UPS functions can be modified using the "UPS Driver" software
to better meet the user's needs.
See "Frequency-regulation rate".
This function shuts down the UPS when it operates on battery power
and no load is detected on the UPS output.
This function makes it possible to energize the connected equipment even
when AC input power is not available (operation exclusively on battery power).
The range of frequency supplied by the AC-power source within which
the UPS can operate in ON-LINE mode (double conversion).
Uninterruptible Power Supply.
It is possible to enable or disable use of UPS ON / OFF controls
by the computer-system protection software.
