2-4. UPS Installation for a Parallel System
If the UPS is only available for a single operation, you can skip this section.
1) Install and wire the UPS according to the section 2-3.
2) Connect the output wires from each UPS to an output breaker.
3) Connect all output breakers to a major output breaker. This major output breaker will then be directly
connected to the loads.
4) Each UPS is connected to an independent battery pack.
NOTE:
The parallel system cannot use one battery pack. This would cause permanent system failure.
5) Refer to the following wiring diagram:
