Ethernet Terminal
Series 8187
7.3
Installation
7.3.1 Ethernet Cable Connection
7.3.2 Terminal Assignment
• Terminal numbers are printed on the base board.
• Each Ethernet terminal is connected straight through to the Ethernet terminal
opposite it.
• Because the core pairs in an Ethernet cable are not usually numbered in ascending
order, the Ethernet terminal designations have been chosen such that the cores can
be connected in pairs to a two-pole terminal block.
Example of an Ethernet connection:
15477E00
• Strip the Ethernet cable
(see figure, dimensions c and d).
The shielding must protrude
20 to 25 mm from the sheath.
• Strip the core ends in the
specified areas (see figure,
dimensions a to c). Keep the core
pairs twisted as far as possible.
• Insert the cores into the Ethernet
terminals, routing them as directly
as possible in order to prevent
signal loss and interfering signals
as far as possible.
