Uptime Institute New York has created the interna
tional Tier classification system for the
infrastructure data centers.
ENERTRONIC modular UPS systems with true online double-

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). EN/IEC 62040-3 UPS-Solution
