Note:
1. For single input connection, please select the larger conductor size cross-
section.
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. If the load in a 3-phase output mode is unbalanced, the L wire of the bypass
and output may exceed the rated current by 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.
Please refer to the following table for conductor’s terminal selection:
