In a parallel system, the length and specifications of power cables on each UPS
should be the same to achieve current equalization in bypass mode. The power
cables include bypass input power cables and UPS output power cables.

The recommended cross-sectional areas of AC power cables in the table are
based on the default 380 V AC current and are compatible with 400 V AC and
415 V AC application scenarios. For details about the current values, see the
current parameters in the technical specifications.
The cables need to be selected according to the site survey data. The cable
recommendation is for your reference only.
The cables must be flame-retardant, and the flame spread rating of the
cables must meet the UL 1581 VW-1, IEC 60332-3-22 (ZB), or higher
requirements.
When selecting, connecting, and routing cables, follow local safety regulations
and rules.
When the external conditions such as cable routing or ambient temperature
change, perform verification in accordance with the IEC 60364-5-52 or local
regulations.
When lead-acid batteries are used, it is recommended that the battery cable
specifications be selected based on forty 12 V batteries by default and
compatible with application scenarios with 30–50 batteries.
When SmartLi batteries are used, it is recommended that the battery input
cable specifications be selected according to the IEC-60364-5-52 standard and
SmartLi user manual
When the mains input and bypass input share a power source, configure
mains input power cables as input power cables.
The cables listed in the tables are used only when the following requirements
are met:
– Multi-core cables are recommended for the mains and bypass input and
output power cables, and single-core cables are recommended for the
battery cables.
– Routing mode: Mains and bypass input and output power cables are
routed over a ladder or bracket (E in IEC 60364-5-52), and the distance
between cables is greater than twice the cable diameter. Battery cables
are routed over a ladder or bracket in a single layer (F in IEC
60364-5-52).
– The ambient temperature is 30°C.
– The AC voltage loss is less than 3%, and the DC voltage loss is less than
1%.
– Cable type: copper flexible cable whose conductor supports the maximum
operating temperature of 90°C
– It is recommended that AC power cables be no longer than 30 meters
and DC power cables be no longer than 50 meters.
