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
3.6.1 Recommended cross-sectional areas for power cables
◆
For future expansion purpose, it is economical to install power cable according to the full rating
capacity initially. The diameter of cable is shown bellow:

◆ 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 30–50 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
the following requirements are met:
− Routing mode: Routing the cables over the cable ladder or bracket in a single layer
(IEC60364-5-52 middle E).
− The ambient temperature is 30°C.
− The AC voltage loss is less than 3%, and the DC voltage loss is less than 1%.
− 90°C copper flexible cable.
− The length of the AC power cables of a UPS is no longer than 30 m and DC power cables
no longer than 50 m.
