4 Cabling the AC 800F

4-22

Connect the 10Base2 cable to ground on the 10Base2 module of every AC 800F, as

shown in Figure 4-12.

Protect the unsheathed metallic 10Base2 F-connectors and 10Base2 cable

connectors from any contact with ground or conductive parts of the building, e.g. by

using an insulating sleeve.

Proceed as follows:

• Strip off the insulating

sheath from one of the two

cables at about 2 cm (not

too close to the connector to

avoid sharp-edged cable

kinks).

• Fasten the braided cable

shield to the contact ledge on

AC 800F using clip TV 83xF

4.2.7.3 Connecting 10Base2 nodes while the system is running

In many cases, the engineering station is only temporarily connected to the AC 800F.

There are three ways to connect and disconnect the engineering station while bus

operation is in progress:

1. Connection via 10Base2 F-connector

This is the easiest way to connect or disconnect a node to/from the network

without requiring additional material. Proceed as follows to disconnect the node:

Switch off

engineering station.

Disconnect 10Base2 F-

connector from

engineering station.

Avoid shorts with ground or

any conductive parts of the

building.
