3.5 Power Cables
◆
The cable design shall comply with the voltages and currents provided in this section, Kindly
follow local wiring practices and take into consideration the environmental conditions
(temperature and physical support media).
WARNING!
UPON STARTING, PLEASE ENSURE THAT YOU ARE AWARE OF THE
LOCATION AND OPERATION OF THE EXTERNAL ISOLATORS WHICH ARE
CONNECTED TO THE UPS INPUT/BYPASS SUPPLY OF THE MAINS
DISTRIBUTION PANEL.CHECK TO SEE IF THESE SUPPLIES ARE
ELECTRICALLY ISOLATED, AND POST ANY NECESSARY WARNING SIGNS TO
PREVENT ANY INADVERTENT OPERATION

◆ When selecting, connecting, and routing power cables, follow local safety regulations and rules.
◆ If external conditions such as cable layout or ambient temperatures change, perform
verification in accordance with the IEC-60364-5-52 or local regulations.
◆ If the rated voltage is 400 V, multiply the currents by 0.95. If the rated voltage is 415 V,
multiply the currents by 0.92.
◆ If primary loads are non-linear loads, increase the cross-sectional areas of neutral
wires1.5–1.7 times.
◆ The nominal battery discharge current refers to the current of forty 12 V batteries at 480V
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.
◆ The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–40 batteries.
◆ When the mains input and bypass input share a power source, configure both types of input
power cables as mains input power cables. The cables listed in Table are used only when
