Bus cable installation
(1) Cable shield
(2) Bus cable (e.g. 6XV1 830-0EH10)
- strip insulation, e.g. with stripping tool
6GK1905-6AA00
(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) Insert the cable into the opening (cable shield
must lie bare on the metal guide)
(5) Close the housing cover and screw it shut
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).
