When the primary loads are non-linear loads, increase the cross-sectional areas of the neutral wires
1.5–1.7 times.
When the mains input and bypass input share a power source, configure input power cables as mains
input power cables. In addition, cables listed in
apply only to the following conditions:
Cable routing mode: For the UPS5000-E-(25 kVA-75 kVA), the cables are installed along the wall or
on the floor (IEC-60364-5-52 C standards).
The ambient temperature is 30°C.
The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%. The recommended
cable diameters in
meet the basic through-current requirements. Users should evaluate the
line voltage loss based on the actual cable length. If the voltage loss exceeds the requirements,
increase the cable diameter properly.
The cables are single- or multi-core 90°C soft power cables with a copper conductor.
