Note before connecting the device
Note
The varying voltage power supply module is designed for operation on 120/230/240 V AC
networks. The setting of the voltage range takes place automatically.
Do not connect or disconnect power and data cables during thunderstorms.
The device is designed for operation on grounded power supply networks (TN networks 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.
CAUTION
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 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-....".
