Note: Fieldbus PCI cards may only be fitted by qualified personnel in accordance and the following points
must be observed
•
In order to protect the card from electrostatic discharge the user must be discharged before han-
dling the card or the PC.
•
Before opening the PC housing it must be switched off, and the mains plug must be removed.
It may be necessary before fitting to set the Dip-Switch in order to activate the internal CAN / DeviceNet
bus terminating resistors. The card can be fitted into any free PCI slot. Ensure that the PCI bus connector
is making good contact, and that the module is seated firmly. Fasten the module to the PC slot housing
with the fixing screw.
