When the primary loads are non-linear loads, increase the cross-sectional
areas of the neutral wires 1.5–1.7 times.
The nominal battery discharge current refers to the current of forty 12 V
batteries at 480 V in standard configuration.
The maximum battery discharge current refers to the current when forty 12 V
batteries in standard configuration, that is, two hundred and forty 2 V battery
cells (1.67 V/cell), stop discharging.
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
3-2 apply only to the following conditions:
– 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
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.
