2.6 Connecting the Network Cables (AUTROLON)

2.6.1 External AUTROLON Cables

2.6.2 Internal AUTROLON Cable

Note that the polarity of the external AUTROLON cables has no
importance. Likewise, incoming and outgoing external AUTROLON
cables can be freely connected to either LON-A or LON-B (see
drawing on next page). For documentation purposes, however, we
recommend that output is connected to A and input is connected to B.
In high-current environments (power plants, electrical machinery etc.)
it is recommended that shielded cable is used. In this case, the
shielding of the cable stubs between each cabinet should only be
connected at one end to avoid ground loops. If high-frequency noise is
expected (>10MHz), then both ends should be connected. This may
be present close to radio transmitting equipment or similar.
The internal AUTROLON cable is connected between the Connection
Module BSF-310B and the LON Interface Board EAU-310 (see
drawings below and on next page).
NOTE:
Make sure that the connector on each side is mated correct and
is connected to all pins on the 4-pin terminal, and that the wires
point downwards on the BSF-310B board, and inwards on the
EAU-310 board.
