When selecting, connecting, and routing power cables, follow local safety regulations
and rules.
When the external conditions change, for example, the cable layout or ambient
temperatures, perform verification in accordance with the IEC-60364-5-52 or the 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.
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.
The battery cable specifications are selected based on 40 batteries by default and
compatible with application scenarios with 30–46 batteries.
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 Table 3-3 apply only to
the following conditions:
− 200 kVA: The cables are installed along the wall or on the floor (IEC-60364-5-52 C
standards). 300 kVA: The cables are routed over a ladder or bracket in a single layer
(IEC60364-5-52 F standards).
− The ambient temperature is 30°C.
− The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
− 200 kVA: single- or multi-core 90°C soft power cable with a copper conductor; 300
kVA: single-core 90°C soft power cable with a copper conductor.
− It is recommended that the 200 kVA AC power cable should not be longer than 30
meters and the DC power cable should not be longer than 40 meters. The 300 kVA
AC power cable should not be longer than 30 meters and the DC power cable
should not be longer than 50 meters.
Table 3-4 and Table 3-5 list the requirements for power cable terminals of the
UPS5000-E-200K-SM/FM.
