Power Consumption - Siemens Panel PC 677 Operating Instructions Manual

Power Factor Correction
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 the normal and buffered mode are
identified with the classification "VFI-SS-...." or "VI-SS-....".
Notice
Risk of damage
Operation of the device on a non-sinusoidal mains voltage can cause damage to the power
supply unit.
Country-specific Connection Information
For the USA and Canada
For the United States and Canada, a CSA or UL-listed power cord must be used. The
connector must be compliant with NEMA 5-15.
Country-specific power cables are available as accessories.
