"Monitor" alphanumeric display (cont.)

Voltage measurements

These measurements may be accessed in two manners:

Display of voltage measurements

◗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.

Current measurements

These measurements may be accessed in two manners:

Display of current measurements

◗pressing the "A" button displays the series of screens in the figure opposite;

◗in "Monitor" multi-cubicle mode, pressing the ">" button when the screen already displays the current measurements of a cubicle.

The system shifts to the current measurements of the next cubicle.

Note:

◗Mains 2 measurements are not displayed on UPS cubicles in parallel UPS systems;

◗Mains 1 and inverter output measurements are not displayed on Static Switch Cubicles.
