In case the communication cable is removed or damaged during parallel operation and the communication is
lost then the slave UPS which cannot communicate with the master UPS will disconnect from the output bus
and turn off. The other UPSs will continue normal operation. In such a case, this UPS should be turned off
completely in order to insert its communication cable again and then switched on again.
CAUTION:
Do not remove the communication cabl
es between the UPS’s during parallel
operation.
CAUTION:
Do not try to insert its communication cable while it is operating.
The Redundancy System expects to have at least one more UPS than N value. Otherwise it
shall provide
“Redundancy Lost”
alarm. The same alarm shall also appear in case:
Load % > N / ( N+1 ) * 100
