Grounding the Module

Minimum Spacing

Maintain spacing from enclosure walls, wireways, and adjacent equipment. Allow 50 mm (2 in.)
of space on all sides for adequate ventilation, as shown.

Panel Mounting

Mount the module to a panel by using two screws per module. Use M4 or #8 panhead screws.
Mounting screws are required on every module.

Panel Mounting Using the Dimensional Template

Panel Mounting Procedure Using Modules as a Template

The following procedure allows you to use the assembled modules as a template for drilling holes
in the panel. If you have sophisticated panel mounting equipment, you can use the dimensional
template provided on page

8

. Due to module mounting hole tolerance, it is important to follow

this procedure.

1.

On a clean work surface, assemble no more than three modules.

2.

Using the assembled modules as a template, carefully mark the center of all
module-mounting holes on the panel.

3.

Return the assembled modules to the clean work surface, including any previously
mounted modules.

ATTENTION: This product is intended to be mounted to a well-grounded mounting
surface such as a metal panel. Additional grounding connections from the power
supply's mounting tabs or DIN rail (if used) are not required unless the mounting
surface cannot be grounded. Refer to Industrial Automation Wiring and Grounding
Guidelines, Rockwell Automation publication

1770-4.1

Spacing for single-wide modules 35 mm (1.378 in.).

NOTE: Overall hole spacing
tolerance: ±0.4 mm (0.016 in.).

Spacing for one-and-a-half-wide modules 52.5 mm (2.067 in.).

Locate holes every 17.5 mm (0.689 in.) to allow for a
mix of single-wide and one-and-a-half-wide modules
(for example, the 1769-OA16 module).
