Operating Instructions, 09/2018, A5E45118479-AA
Note
Operation at an uninterruptible power supply (UPS)
The power supply contains an active PFC (Power Factor Correction) circuit to conform to the
EMC guidelines.
Uninterruptible AC power systems (UPS) must supply a sinusoidal output voltage in the
normal and buffered mode when used with SIMATIC PCs with an active PFC.
UPS characteristics are described and classified in the standards EN 50091-3 and IEC
62040-3. Devices with sinusoidal output voltage in normal and buffered mode are identified
with the classification "VFI-SS-...." or "VI-SS-....".
