Information about the power supply
Note
Note the following points:
The wide-range power supply is designed for 100 to 240 VAC power supply systems.
setting of the voltage range takes place automatically.
The power supply contains a power factor correction circuit to conform with the EMC
directive.
Uninterruptible AC power systems must supply a sinusoidal output voltage in the normal
and buffered mode when used with SIMATIC PCs with a PFC circuit.
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-....".
Localized information
230 V supply voltage
outside of the USA and Canada
This device is equipped with a safety-tested power cord which may only be connected to a
grounded shockproof power outlet. If you choose not to use this cable, you must use a
flexible cable of the following type: Cable cross-section at least 0.82 mm
2
and 15 A / 250 V
ground contact connector. The cable set must be compliant with the safety regulations of the
country where the device is to be installed and carry the identification labels required by law.
Operation in 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.
Use a flexible power cord which is approved to UL and CSA with the following features: SJT
model with three leads, min. 18 AWG conductor cross-section, max. 4.5 m in length and
parallel ground contact connector 15 A, min. 125 V.
Use a flexible power cord which is approved to UL and CSA with the following features: SJT
model with three conductors, min. 18 AWG conductor cross-section, max. length 4.5 m, and
tandem grounded connector 15 A, min. 250 V.
