Step 10 Check that parameters of the local UPS are automatically synchronized to the
other UPS in the parallel system.
Figure 5-11 Synchronizing parallel parameters
Step 11
Set battery sharing for each UPS based on site requirements.
Figure 5-12 Setting battery sharing
This step applies only to the UPS2000-G-15KRTL-01 and UPS2000-G-20KRTL-01.
Step 12 Perform "startup operations" on each UPS in the parallel system.
The parallel system transfers to normal mode.
After you perform "startup operations" on UPS 1 to UPS
n
one by one, UPS 1 to UPS
n
are
starting. If you do not perform "startup operations" on the other UPSs in 5 minutes, UPS 1
to UPS
n
enter normal mode, and the other UPSs supply no power.
Step 13 When the parallel system runs properly, switch on the general output circuit
breaker Q (provided by the customer), and start loads one by one.

5.3.3 Shutting Down the Parallel System
Shutting Down a Single UPS in the Parallel System
Step 1 Perform "shutdown operations" twice on a single UPS within 30 seconds (for
example, UPS 1 in the parallel system wiring diagram) in the parallel system. The
UPS shuts down. The other UPSs continue working.
The UPSs in the parallel system have shut down supply no power (the mains indicator,
bypass indicator, and battery indicator are o).
