• Do not operate the device via non-grounded or impedance-grounded networks (IT
• Operate the device only in grounded power networks (TN networks in accordance with
Note
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-....".
Note
The power supply of the device contains a PFC (Power Factor Correction) circuit to conform
to the EMC directive.
