I/O chassis

keying bands
(cat. no. 1777RK)
use these numbers
as a guide
Use the numbers to the right of the backplane socket as a guide when
positioning the keying bands.
See the installation instructions for the keying position of each I/O module.
Do not place any I/O modules in the left-most slot. Your processor
goes there.
ATTENTION: If keying bands (in general) are not installed, a
module inserted into a wrong slot could be damaged by
improper voltages connected through the wiring arm. Short
circuits on the I/O module can result from misalignment if
keying bands are not installed.
Snap each field wiring arm onto the lower horizontal bar of the I/O chassis
(Figure 4.15). When I/O modules are in place, the field wiring arm pivots
and connects to the module.
