NOTE !
UPS system has been turned
OFF
following the
“Maintenance shutdown (Load on Q2)”
procedure and the load is still powered by
manual bypass Q2.
The

input.
2. Close the input rectifier switch Q4 (Pos. I).
LED 1 (input mains rectifier)
must be lit and
LED 3 (rectifier)
must blink.
The rectifier starts up automatically, supplying the DC circuit, and charging the DC capacitors.
The
LED 3 (rectifier)
stops blinking and stays ON, indicating that the DC link has reached the floating voltage.
3. Battery coupling to DC link.
After awhile, the
green LED LD1
next to the battery fuse carrier,
F8 – F9
lights up, indicating the rectifier
supplies the floating voltage.
After checking the right polarity, connect the battery to the DC-link by closing
