NOTICE
Operation with uninterruptible power supply
An uninterruptible AC power supply (UPS) must be used when this device is operated with
a PFC (Power Factor Correction) circuit that supplies a sinusoidal output voltage in normal
and buffer mode.
UPS characteristics are described and classified in the standards EN 50091-3 or
IEC 62040-3. Devices with sinusoidal output voltage in the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
