5. OPERATION.
5.1.
START UP AND ShUTDOWN.
Starting up the UPS with mains voltage (Line mode).
1.
a.
After making sure that the connection with the power
supply is correct, turn ON the circuit breaker of the bat-
tery module (models with extended autonomy only) and
the input one, keeping this order. From now on the fan
will start up and the UPS will supply power to the loads
through the bypass line. The UPS is on bypass mode, code
«01».
Start up the UPS by pressing for more than 1 second the
b.
ON button. The buzzer will beep once.
A few seconds later, the UPS switches to Line mode, code
c.
«02». If the mains voltage is not correct, the UPS will run
on Battery mode without breaking the output voltage.
Starting up the UPS without mains voltage (Battery
2.
mode).
a.
Make sure that the circuit breaker of the battery module is
turned ON (models with extended autonomy only).
Press the ON button for more than 1 second to start up
b.
the UPS. The buzzer will beep once. The UPS will run on
No output mode, code «00».
A few seconds later, the UPS will transfer to Battery
c.
mode, code «03».
Shutdown the UPS with mains voltage (Line mode).
3.
a.
Shutdown the UPS inverter by pressing the OFF button for
more than 1 second. The buzzer will beep once and the
UPS will transfer to Bypass mode.
Once the shutdown is completed, the UPS still has voltage
b.
on its output. To turn it off definitely, just break the mains
voltage and a few seconds later the LCD panel will be
turned off and the output voltage will not be present.
Shutdown the UPS without mains voltage (Battery
4.
mode).
Shutdown the UPS by pressing the OFF button for more
a.
than 1 second. The buzzer will beep once.
Once shutdown, the UPS will transfer to No output mode.
b.
Finally the LCD panel will be turned OFF and there will not
be output voltage.
Advice
: Turn off the connected loads before starting up
the UPS. Later, once the UPS runs on INV mode, connect
them one by one. Turn off all the loads before turning off
the UPS.
5.2.
PARALLEL OPERATING (NOT fOR MODELS IN RACk
19’’).
Maintenance of the parallel device.
1.
This UPS has a parallel device. To add or remove units from the
system, follow the next procedure:
Procedure to add a new UPS.
2.
Before installing it, prepare the input and output wiring,
a.
switches and parallel cable.
Turn OFF the input and output breakers of the new unit.
b.
Connect its input, output and battery cables. Remove the
bridge between JP1 and JP2 in the terminal strip.
Shutdown the UPSs that are started up. Once all the UPSs
c.
are transferred to bypass, remove the cover of the main-
tenance bypass of each UPS, change the position of the
maintenance switch from «UPS» to «BPS» and turn OFF
the input circuit breaker of each UPS.
If the UPS that it is started up is single, remove also the
d.
bridge between JP1 and JP2 of the terminal strip.
Remove the cover of the parallel port from the new UPS,
e.
push one side of the parallel cable into the parallel kit slot
and screw the connector; screw the parallel cover back.
Remove the maintenance bypass cover from the new
f.
UPS and change the position of the switch from «UPS»
to «BPS».
Turn ON the battery switch and the external circuit breaker
g.
of the new UPS; measure the voltage difference between
the output of the new UPS and the parallel system, in
order to check if the voltage difference is lower than 1
V. If yes, turn ON the output circuit breaker. If the voltage
difference is higher than 1 V, check the wiring.
Remove the cover of the parallel port card located in the
h.
UPS, which has been done the maintenance bypass trans-
ference, and push the other parallel cable side into the
parallel kit slot and fix the connector. Screw the cover of
the parallel port back.
Turn ON the input circuit breakers of all UPSs (including
i.
the new one) of the parallel system. Once all have trans-
ferred to Bypass mode, screw the maintenance bypass
cover back.
Start up each UPS and check its LCD panel. Make sure
j.
that each UPS has a normal operating and all has trans-
ferred to INV mode together. Measure the voltage in JP1
and JP2 in the terminal strip of each UPS in order to check
if the voltage difference is lower than 1 V. It the quoted
difference is higher than 1 V, the output relay of the UPS
can’t be closed.
Measure the voltage between each JP2 of each UPS to
k.
check if the voltage difference is lower than 5 V (usually
2 V). If the difference is higher than 5 V, it means that the
new UPS has to be set again or the parallel cable of the
parallel kit has to be checked.
