6.6.3. Setting the parameters on the display screen.
The setting on the display will be the following, Fig. 61:
1.
Choose the operating mode: Parallel
2.
Enter the number of the UPS in parallel: 2 or 3.
3.
Enter the identification of each cabinet: for 2 UPSs, the first
will be 0 and the second 1; for 3 UPSs, the first will be 0,
the second 1 and the third 2.

Settings screen for the parallel system.
4.
Keep the rest of the parameters of each UPS if there is no
special requirement (keep the default settings), as shown
in Fig. 62.

5.
Check the label of each UPS to ensure that the model,
voltage and frequency are the same.
UPSs in 6-slot cabinets can only be paralleled with
6-slot cabinets, never with 10-slot cabinets; the same
must apply with 10-slot cabinets.
6.
Once the above settings have been made, turn off the UPS
and restart it for the changes to take effect:
a.
If there are 2 UPSs in parallel: the first should appear as
(P-0/2) and the second as (P-1/2).
b.
If there are 3 UPSs in parallel: the first should appear
as (P-0/3), the second (P-1/3) and the third (P-2/3), as
shown in Fig. 63.

6.6.4. Connection of parallel cables.
The control cables for parallel operation must connect all de-
vices in a ring, as shown in Fig. 64.

6.6.5. Verification of the parallel system.
Once all of the connections have been made, it is necessary to
verify that the system is working properly.
To do so, taking as an example the system with three cabinets
connected in parallel shown in Fig. 55, follow these steps:
1.
First close the OS1 protection and then BS1 and MS1: the
first UPS will start automatically. After about 2 minutes, the
first UPS will have completed the startup and closed the
battery protection of the first UPS. At this point, no alarm
should appear on the display; verify that the same informa-
tion shown on the nameplate of the devices characteristics
is shown on the screen. If startup fails, contact an engineer
or your distributor.
2.
Open the battery protection of the first UPS, then also open
BS1 and MS1, and finally open OS1: the first UPS should
shut down completely.
3.
Operate the second and third UPS as with the first men-
tioned above.
4.
After the previous switching and with the confirmation
that there is no anomaly, close OS1, OS2 and OS3 first,
one by one, then close BS1, BS2 and BS3, one by one, and
