3.2.4 Select Input Breaker
We suggest to add a breaker (we suggest to select the breaker with feedback double pole
disconnection equipment) that matches the UPS power at the front of the UPS input to
insulate the mains. Considering the UPS charge power and the impact current while power
on, the selected breaker must be 1.5 to 2 times of UPS input max. current, and cannot with
leakage protection, which is to avoid wrong action of breaker. The breaker of DC input should
be select more than the 250V DC.
