Connect 100-240 Vac Power Supply - Siemens SIMATIC IPC477D Operating Instructions Manual

Mounting and connecting the device
3.4 Connecting the device
3.4.2.2

Connect 100-240 VAC power supply

The following procedure applies to a device that is connected to a 100 VAC - 240 VAC
(-15 % / +20 %) power supply system, 50 - 60 Hz. The power consumption at 240 V can be
up to 90 W, depending on device.
General connection information
Note the following in order to operate the device safely and according to regulation:
Note
The wide-range power supply is designed for 100 to 240 VAC power supply systems. It is
not necessary to adjust the voltage range. The permitted nominal voltage of the device must
conform with local mains voltage.
Note
Do not connect or disconnect power and data cables during thunderstorms.
Power supply system
The device is intended for operation on grounded power supply systems (TN systems
according to VDE 0100, Part 300, or IEC 60364-3).
It is not designed for operation on ungrounded or impedance-grounded power networks (IT
networks).
Note
Power disconnection
The power plug must be unplugged to fully isolate the device from mains. This location must
be easy to access. There must be a central disconnector switch if the device is mounted in a
control cabinet.
Always ensure that the socket on the device is freely accessible or that the grounding-type
receptacle of the building installation is freely accessible and located as close as possible to
the device.
Note
The power supply contains an active PFC (Power Factor Correction) circuit to conform to the
EMC guidelines.
Uninterruptible AC power supplies (UPS) must supply a sinusoidal output voltage in the
normal and buffered mode when used with SIMATIC IPCs 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-....".
