4.1.1 Circuit Breakers
There are four circuit breakers on the rear side of the device.
These are used for the AC input, maintenance bypass, output and the battery connections
respectively.
Three-phase AC voltage is applied through
CB1
to input of UPS.
AC input voltage will be applied directly to loads through
CB2
. In this way, maintenance
purposed switching is done properly. If UPS is actived while it is working thanks to auxilary
short circuit info located in CB3, mains makes the bypass static switches actived. The system will
be switched to maintenance mode smoothly.
CB3
is used to connect or seperate AC voltage that come from static switches to the loads on
UPS
.
External batteries are connected to UPS through
CB4.
CB5
is used as an external bypass switch.
