(3) Contact cover for insulation-piercing connecting device
- insert the green and red cores into the open contact cover right up to the end
- close the contact cover (press it down as tight as possible)
(4) The cable shield has to lie flat on the shield plate, the cable jacket has to end before the shield
plate
(5) Close the housing cover and screw it shut
(6) Switch for terminating resistor
(7) Stripping tool 6GK1905-6AA00
Note: The bus cables are connected by means of an insulation piercing technique (Fast Connect
connection system). The insulation piercing connecting devices are designed for 10 connecting
cycles. If you wish to reconnect a line that has already been connected, you must crop it first.
Bus connection for the first and last node on PROFIBUS Cable must always be connected on the left
(see label A1, B1) Switch position must be "ON" for the first and last node on the PROFIBUS.
(Terminating resistance connected). Bus connection for all other nodes on PROFIBUS Cable feed
must always be connected on the left (see label A1, B1). Cable extension must always be connected
on the right (see label A2, B2). Switch position must be "OFF" for all other nodes on the PROFIBUS.
(Terminating resistance disconnected).
Note if the terminating resistor is used on the Profibus connector then do not use the switch inside
the Anybus unit as well.
