4. Connecting and grounding the AUI cable
Link the node with the transceiver using the AUI cable. Plug the AUI cable side
with the slide lock to the transceiver and lock. Then connect the other side to AUI
module and lock, too. Make sure that the AUI module lock at the front snaps in.
Use grounding clip TV 83xF to ground the AUI cable of the AC 800F on the
contact ledge. Proceed as shown in Figure 4-17.

If the installation is not grounded as described above, the operational
reliability, RFI suppression and EMI/RFI shielding is not guaranteed.
Do not lay the AUI cable close to power cables.
4.2.8.4 Connecting and disconnecting nodes while the system is running
Transceivers can be connected while the system is running. However, drilling chips
may cause short circuits.
When disconnecting a node while the system is running proceed as follows:
• Switch off the node
• Disconnect the AUI cable
• The transceiver itself remains connected to the 10Base5 cable.
The 10Base5 tap remains in the cable. Do not remove the 10Base5 tap when no
node is connected. If required detach the transceiver from the tap and protect the
contacts with the cap delivered with the unit.
