leads to a drop in battery capacity. To prevent this, delayed start function
was implemented.
Table 2.8.2-2
– Indication of UPS state
VBAT VOUT VAC
Description
The switch operates from the power grid,
battery is present, the battery voltage is normal.
The switch operates from the power grid,
battery failure (battery not connected, wrong
polarity or terminals are closed)
The switch operates from the battery (battery
voltage is above 46V), supply voltage is absent.
The switch operates from the battery (battery
voltage is below 46V, but above 42V), supply
voltage is absent. Blinking of VBAT light diode
indicates, that the battery is low.
The switch is completely de-energized, or
is in sleep mode with discharged
battery.
The switch is in
delayed start mode and is expecting
the 220V supply.
