Chapter 7
Installing 1771 I/O
7-12
Install the I/O modules, including wiring between wiring arms and various
input and output devices. If you follow this procedure carefully, you can
minimize wiring errors. You must place each I/O module correctly, and
make every I/O connection at the proper wiring-arm terminal.
Color-coded labels identify the various types of I/O modules. Also, other
labels allow you to write in the address of each I/O terminal.
Insulation color is useful for identifying various groupings of wires. For
example, the Bulletin 1790 Assembled Systems, optionally available from
A-B Quality and Productivity Systems Division, typically have red ac
wires and blue dc wires. However, follow all local electrical codes.
Several I/O modules require shielded-cable connections. We give you
shielded-cable-connection instructions (page
7-17 ), which supplement the
general instructions in this section.
This installation procedure is necessarily general in nature. Many types of
I/O modules are available, and the connections vary according to module
type. The specific wiring required for each type of I/O module is in the
separate installation data publication for that specific module type.
Therefore, see
Figure 7.7 and the appropriate installation data publication
during execution of the following steps.
ATTENTION: Do not force a module into a backplane
connector; if you cannot seat a module with firm pressure,
check the alignment and keying. Forcing a module can damage
the backplane connector or the module.
