and the load is still powered by the maintenance switches
Q2
.
The load must be transferred back to the UPS system
.
Open the front door and make sure that:
a)
The
safety screens
are fixed in their position.
b)
The
switches
Q1
and
Q4
are OFF
(0) and the external
battery circuit breaker or battery fuses are
open
. The
switch Q2
must be closed.
c)
The electronic power supply and the control panel are ON.
LEDs 2, 8, 9, “alarm”
and
“service

2. Close the input switch Q4.
LED 1
must be lighted and
LED 3
(inside rectifier symbol) must blink.
The rectifier starts up automatically, supplying the DC circuit, and charging the DC capacitors.
After some seconds, the
contactor K3
closes (the green
LED 1 - K3 ON
on
“P1 - Power Interface”
lights
up, see
Fig. 4.8.2-1
).
The
LED 3
(inside rectifier symbol) stops blinking and stay ON, indicating that the DC link has reached
the floating voltage.
3. Battery coupling to DC link.
Close the external battery circuit breaker or battery fuses, after checking the right polarity.
The
battery
is now connected to the DC link.
LED 4b
should be lit indicating battery charge.
The
buzzer
switch OFF and LED

LED 5
(inside inverter symbol) blinks.
In a short time, when the inverter voltage is confirmed, the LED stops blinking and stays continuously
lit. The
load
will be automatically transferred from mains to
inverter
.
LEDs 1, 2, 3, 4b, 5, 6
and
8
are now lit.
LEDs 4a, 7
and
