4.3.2 Wiring operation

1. Remove the protective cover of the UPS
2. Install the copper bars provided with the UPS to the input ends of the additional distribution box
according to the wiring mode and connect the wires. While connecting the wires, connect the lower row
of wires first and then connect the upper row of wires.
Since the distribution box is equipped with connection cables (AC INPUT, BYPASS, AC OUTPUT)
for the connection to the UPS, the copper bars provided with the UPS must be moved to the input end
of the distribution box.
For example, if the UPS adopts 1/1 mode wiring, the copper bars on the UPS (3PIN copper bar of AC
INPUT and 2PIN copper bar of Input N) should be moved to the terminal bar of the distribution box, and
then, the UPS connection terminals of the distribution box should be connected one-to-one with the UPS.
