The overall cable diameter and the cross-sectional area
of the three wires depends on the UPS rating.
Power and equipment connections:
1. Remove the terminal-block cover .
2. Insert the cable supplying the equipment and the power
cable through the cable clamps .
3. Connect the three wires of the equipment cable to the output
