15000/20000 VA
Required cable cross-sections 16U Frame
Terminal-block cable capacity: 25 mm
◗
Capacity for ground conductor: 25 mm
◗
Recommended upstream protection – 10U Frame
UPS Power Rating
5000/10000 VA
The indicated protection ensures discrimination for each output circuit downstream of the UPS. If these recommenda-
tions are not followed, protection discrimination is not achieved and may result in a potential power interruption to the
connected devices.
