Parallel Overview Kit - PROLiNK Giant II Series User Manual

UPS failure. During normal operation, the load is evenly divided across all UPS, which behaves as if they
were a single UPS device. If one UPS fails or needs to be turned off to maintenance, then the system will
continue to run without interruption. UPS modules must be the same size so that the anticipated total load
can be carried by N units. If the total power of the system is more than N units, the system will continue to run
but with an exit warning.
➢ Expansion enabled when the total power on the system is more than N units. In this case, the system
continues to run but with an alert ringing. In this situation, if one UPS fails or needs to be shut down for
service, the system will shut down because Overloaded.
➢ Master and slave randomly generated. Usually the first to start will be the master.
If one slave device fails or needs to be turned off, then the master and other slaves keep running. If
The master fails or needs to be turned off, then the new master will come out of the slave by competing
one each other.
