5.2 Connecting the device to power

5.2 Connecting the device to power
Note before connecting
Do not connect or disconnect power and data cables during thunderstorms.
The device may only be operated on grounded power supply networks (TN systems to VDE
0100, part 300, or IEC 60364-3).
Operation on ungrounded or impedance-grounded power networks (IT networks) is
prohibited.
The permitted nominal voltage of the device must conform with local mains voltage.
The mains connector must be disconnected to fully isolate the device from mains. Ensure
easy access to this area.
A master mains disconnect switch must be installed if the device is mounted in a switch
cabinet. Always ensure free and easy access to the power inlet on the device or that the
safety power outlet of the building installation is freely accessible and located close to the
device.
Note
The wide-range power supply module is designed for operation on 100 VAC to 240 VAC
mains. The setting of the voltage range takes place automatically.
Note
The power supply contains a PFC (Power Factor Correction) circuit to conform with the EMC
directive.
Uninterruptible AC power systems (UPSs) 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-....".
