6. Appendices
Frequency-regulation rate
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".
Hot swap
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.
Install
Connection module (with manual bypass) offering terminal blocks
for connection to the AC-power source and the equipment.
Manual bypass
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.
ON-LINE mode
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.
Percent load
Ratio between the power drawn by the connected equipment and the total
power that the UPS can supply.
Personalization
A number of UPS functions can be modified using the "UPS Driver" software
to better meet the user's needs.
Redundancy
See "Frequency-regulation rate".
Sleep mode
This function shuts down the UPS when it operates on battery power
and no load is detected on the UPS output.
Start on battery power
This function makes it possible to energize the connected equipment even
when AC input power is not available (operation exclusively on battery power).
Tolerance for AC-power
The range of frequency supplied by the AC-power source within which
source frequency
the UPS can operate in ON-LINE mode (double conversion).
UPS
Uninterruptible Power Supply.
UPS ON / OFF
It is possible to enable or disable use of UPS ON / OFF controls
via software
by the computer-system protection software.
