Connecting 6.2 Connecting the 100 V to 240 V AC power supply

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

A UL-listed power supply cable must be used in the United States and Canada.

Power cables are provided as an accessory for the specific country of delivery.

120 V supply voltage

Use a flexible power cable with UL approval and the following features: Type SJT with three leads, min. 18 AWG conductor cross-section, max. 4.5 m long and parallel 15 A ground contact connector, minimum rating 125 V.

230 V supply voltage

Use a flexible power cable with UL approval and the following features: Type SJT with three leads, min. 18 AWG conductor cross-section, max. 4.5 m long and tandem 15 A ground contact connector, minimum rating 250 V.

For countries other than the USA and Canada

Please note local supply voltages

This device is equipped with a safety-tested power cord which may only be connected to a ground contact power outlet. If you choose not to use this cable, you must use a flexible cable of the following type: Min 18 AWG conductor cross-section and 15 A / 250 V shockproof connector. The cable set must be compliant with the safety regulations and stipulated IDs of the country where the system is to be installed.
