3. To complete the connection by plugging the connector of the
external battery cable into the external battery socket of the UPS.
Do not attempt to connect any loads to the UPS now. You should
connect the input power wire to the right position first. And then
set the breaker of the battery pack in the
“
ON
”
position. After that
set the input breaker in the
“
ON
”
position. The UPS begins to
charge the battery packs at the time.
5.4 Parallel operation
1. Brief introduction of the redundancy
N+X is currently the most reliable power supply structure. N
represents the minimum UPS number that the total load needs; X
represents the redundant UPS number, i.e. the fault UPS number
that the system can handle simultaneously. The bigger the X is, the
higher reliability of the power system is. For occasions where
reliability is highly depended on, N+X is the optimal mode.
As long as the UPS is equipped with parallel cables, up to 3 UPSs
can be connected in parallel to realize output power sharing and
power redundancy.
The blue & brown or red wires for connection to the
positive terminal of the battery pack output
The black & white or black
wires for connection to the
negative terminal of the
battery pack output
The green and yellow ribbon wire
for connection to the ground of
the battery cabinet
The receptacle for
connecting the UPS
