ENERTRONIC modular UPS systems with true online double-
conversion technology are classified level VFI-SS-111 in
accordance with EN/IEC 62040-3.
According this topology four Tier levels (I-IV)
are used:
Tier Non-redundant
Tier II: Basic redundant
Tier III: Concurrently maintainable (No shutdowns for
equipment replacement and maintenance)
Tier IV: Fault tolerant (Withstands single unplanned
event). Outage blackouts
