ON/ENTER button
— system, prepare the input/output Wire,
5.4.2-2
circuit breakers and a main maintenance
Parallel cable
mechanical switch or static switch.
—
5.4.2-3
Current share cable
2. Provide independent battery racks for each
—

UPS.
Connect the
cables to UPS

Figure 5.4.2-1 on a UPS in the system for
more than one second will switch the system
to online mode.

6. Check the output voltage of each UPS
separately, and check whether the output
voltage difference between the units of the
parallel machine system is less than 0.5V. If
the difference is greater than 0.5V, please
contact your local ABB office or an ABB
authorized agent.
7. If the difference in the output voltage is less
than 0.5 V, switch off the input circuit
breaker so that the UPS is off. Connect the
output lines.
8. Remove the cover plate on the UPS parallel
port and connect it one by one with parallel
cable (figure 5.4.2-2) and current share
cable (figure 5.4.2-3) for each UPS and
make sure the cable is reliably connected
(Figure 5.4.2-4). Current share cable and
parallel cable instruction as below:
—
5.4.2-2
—
5.4.2-3
—
5.4.2-4
9. Repeat step 3-8. After these operations, the
system will work normally in parallel mode
(Figure 5.4.2-5).
