System Dimensions
Note: All dimensions are in mm (in.).
Ground the Wiring
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the controller’s
mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded.
Refer to the Allen-Bradley publication
, Industrial Automation
Wiring and Grounding Guidelines, for additional information.
TIP
Compact I/O expansion cables have the same dimensions as the end caps.
Expansion cables can be used on either the right or left end. A 1769-ECR
right end cap or 1769-ECL left end cap terminates the end of the
communication bus.
ATTENTION
This product is grounded through the DIN rail to chassis ground. Use zinc
plated yellow-chromate steel DIN rail to assure proper grounding. The use of
other DIN rail materials (such as aluminum or plastic) that can corrode, oxidize,
or are poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm (7.8 in.) and
use end-anchors appropriately.
