4.1 Input/Output wiring
Please refer to the following table for the UPS wiring (cross-section of
conductor, unit: mm²)
Note:
1. Please select the large cross-section conductor for the UPS input cable in the
single source application.
2. UPS output cable length is recommended not to exceed 10m.
3. UPS default input/output phase mode is: mode 3-1(single source).
4. In the three-phase output mode, if the load is an unbalanced load, the L wire of
the bypass and output may exceed the rated current, and the maximum rated
current will be 1.732 times. The corresponding protection device and wiring
cable must be determined according to the standards of the region and the
actual situation of the user.

Danger!
The rated current of the utility power switch must be greater than the
UPS input current, otherwise the utility power switch may be burnt!
