Voltage measurements
Display of voltage measurements
Direct access to the function
by pressing the "V" button.
Mains 1 input phase-to-phase voltages in V rms
(RC input).
Display of current measurements
Current measurements
Direct access to the function by pressing the "A"
button.
Currents of the three phases at Mains 1 input
in A rms (RC input).
Currents of the three phases at Mains 2 input
in A rms.
These measurements may be
accessed in two manners:
pressing the "V" button displays the
series of screens in the figure opposite;
in "Monitor" multi-cubicle mode,
pressing the ">" button when the
screen already displays the voltage
measurements of a cubicle.
The system shifts to the voltage
measurements of the next cubicle.
Note:
Mains 2 measurements are not
displayed on converters and parallel
UPS with SSC;
Mains 1 and inverter output
measurements are not displayed on
Static Switch Cubicles.
Caution:
For installations comprising a number
of modular UPSs connected in parallel,
the absence of load (UPS output)
voltage indicated on a display is only
valid if it also indicated on the displays
of all the other parallel-connected
UPSs. Before carrying out any work on
a UPS, always check the absence of
voltage using a method complying with
applicable safety rules for work on
electrical equipment.

Mains 2 input phase-to-neutral voltage in V rms.
Mains 2 input phase-to-phase voltages in V rms.
Inverter output phase-to-neutral voltage in V rms.
Inverter output phase-to-phase voltages in V rms.
Load phase-to-neutral voltage in V rms.
Load phase-to-phase voltages in V rms.
Currents of the three phases at inverter output
input in A rms.
Currents of the three load phases in A rms.
Percentage of the current drawn on the most
heavily loaded load phase with regards to the
rated current (in parentheses).
Peak factor for each phase of the load current
with regards to a sine current.
