4 Cabling the AC 800F
4-23
Insulate 10Base2 F-
connector to avoid contact
with ground or conductive
parts of the building.
To connect the engineering station proceed in reverse order. The disadvantage
of this method is that the disconnected 10Base2 F-connector must not have any
contact with ground or any conductive parts of the building.
2. Connection via special junction boxes
If an engineering station is to be frequently connected or disconnected to/from a
10Base2 network it is recommended to use a 10Base2 junction box with
automatic make contact.
These boxes are provided with a micro switch which connects the bus through
when no plug is in the socket. When the plug of a new bus node is connected,
the node is automatically connected into the network. The junction boxes are
available on request.
