3.3.- Menu 2: Measurements display.
To access to this screen press the key ENTER in “2.Measurements display” of the main menu. In this way the user can check,
by moving with the keys < or >, the value of the following electrical measurements:
V phase/neutral = phase to neutral voltage of the input mains.
V phase/phase = phase to phase voltage of the input mains.
Input currents = currents of the three input phases.
V out phase/neutral = phase to neutral voltage of the UPS output.
Output currents = output currents to the load.
Battery V,I = battery voltage and current.
Supplied power KVA = power supplied by the UPS.
Frequency= output frequency of the UPS.
% back up time
Temperature = ambient / rectifier heatsink / inverter heatsink / bypass heatsink / liquid cooling / batteries.
LCD panel goes back to the main screen.
Next there is a list with all the alarms and helping messages.
