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.
4.4 Parallel installation
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 units can
be connected in parallel to realize output power sharing and power
redundancy.
2. Parallel installation
(a) Users need to opt a standard 25-pin communication cable,
which should have 25 cores, corresponding stitches and shield,
as the UPS parallel cable. The length of the parallel cable is
appropriate to be less than 3 m.
(b) Strictly follow the stand-alone wiring requirement to perform the
input wiring of each UPS.
