Connecting and Switching On the Panel PC 670/870 Release 11/02
2–6 SIMATIC Panel PC 670/870 Start-Up Instructions
Operation
The operating unit is operated by touching the touch-sensitive s creen which
contains application-specific functions, e.g. touching a button displa yed.
Continue with Step 11.
Connection Step 11
The Panel PC 670/870 can be operated on AC-120/230 V power supplies . The
voltage selection is performed automatically.
Plug the power cable in the AC/DC power supply connection on the com puter
unit – in the case of a decentralized design, also in the operating unit's AC/DC
power supply connection.
Danger
Since the operating unit does not have a power switch, turning off and
completely disconnecting power requires pulling the power plug.
This location should be easily accessible. For the installation in a cabinet, a
central power disconnect switch must be provided.
Notice
As soon as power is supplied to the operating unit via the power supply
connection, the BIOS and operating system installed are loaded.
If the power supply is switched off during this routine, the operating unit is not
shut down properly. The Scandisk program must then be activated.
To prevent an unintentional unplugging of the power plug from the com puter
unit, we recommend using the power plug lock contained in the accessor ies kit.
In the case of the decentralized design, the operating unit is provided with
cable clips to fasten the power plug.
Notice
A ferrite core is contained in the material supplied with the Panel PC 670.
Connect the ferrite core supplied directly behind the device socket of the power
supply cable.
The operating unit can also be supplied with a DC 24 V power supply,
according to the order option. Plug the 3-point power supply connector in to the
socket on the Panel PC 670/870. Note the pin assignment depicted on the
housing.
When these steps have been completed, continue with Step 12.
