If the UPS is only available for single operation, you may skip this section to the next.
1) Install and wires the UPSs according to the section 2-3.
2) Connect the output wires of each UPS to an output breaker.
3) Connect all output breakers to a major output breaker. Then this major output breaker will directly connect to the
loads.
4) Each UPS is connected to an independent battery pack.
NOTE: The parallel system cannot use one battery pack. Otherwise, it will cause system permanent failure.
