If the 15 kVA/20 kVA UPS uses the BATT.TEMP, MBS, and EPO ports, ensure that the
following operations are performed:
● The BATT.TEMP port is connected to a battery temperature sensor. The cable connected
to the BATT.TEMP port is wrapped with magnetic ring 1 (at least
ve circles).
● The MBS and EPO ports are connected to circuit breakers. The cables connected to the
MBS and EPO ports are wrapped with magnetic ring 2 (at least ve circles).
● Model of magnetic rings 1 and 2: DN85H or E2F
In a UPS2000-G-15 kVA/20 kVA parallel system using the TN-C power distribution
system, there are two scenarios for installing magnetic rings on the UPS mains
input PE cables:
