3.2.3 Select Input Breaker
We suggest to add a breaker (we suggest to select the breaker with feedback double pole
disconnection equipment) or distribution cabinet 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.

distribution box should be manufactured by professional company. The breaker of DC input
should be select more than the 250VDC. The selection of breaker, please referenceTable3-2.
