WARNING
Risk of damage to the operator terminal or corruption of application
software by integrating non-released extension cards!
Install only released extension cards, and have them installed by skilled em‐
ployees.
The PCI slot is provided with the following voltages:
Voltage Maximum current permissible
+5 V 1.2 A
+12 V 1 A
Fig.8-2: Voltages for the PCI card
The voltages are not protected separately, but they are monitored together with
the power supply. Thus, the maximum current cannot be exceeded or a short-
circuit cannot result in a voltage breakdown and therefore not lead to switching-
off of the device.
The voltages -12 V and +3,3 V are not available at the PCI slot.
For the VPP 21, the maximum dimension of an extension card can be:
Height: 123 mm
Width: 20 mm
Depth: 176 mm
8.5.2 PCI Card Installation
If a PCI card should be installed, the following is to be carried out:
1.
Switch off the VPP 21.
2. Open the left door of the rear of the VPP 21. Remove the two ribbon cables
by using the release lever at the shorter sides of the connectors.
Fig.8-3: Position of the ribbon cables
3. Open the right door on the rear of the VPP 21 and remove the cables
connected to the connector panel.
4. Remove both the screws used to fasten the VPP 21 in the housing.
