Optimizes the
performance of the TN-C
power distribution system
in the parallel system
scenario.
In a UPS2000-G-15
kVA/20 kVA
parallel system
using the TN-C
power distribution
system, install four
magnetic rings on
the PE cables on
each UPS, bind the
four magnetic
rings together
using binding tape,
and secure them
to the nearest
place.
● It is recommended that you install the battery temperature sensor (secured with an
adhesive) on the surface of batteries in the middle of the battery rack.
● Check the upstream input power cable connection. If the PE wire and neutral wire are
short-circuited, the system is a TN-C system. If the PE wire and neutral wire are
connected separately, the system is a TN-S system.
