Minimum Space

Maintain spacing, for example, from enclosure walls, wireways, adjacent

equipment. Allow 50 mm (2 in) of space on all sides for adequate ventilation.

Panel Mount

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 Mount Procedure with the Dimensional Template

IMPORTANT

You must use a 1769-ECR or 1769-ECL right- or left-end cap to terminate

the end of the serial communication bus.

ATTENTION: During panel or DIN rail mounting of all devices, be sure that all

debris (for example, metal chips and wire strands) is kept from falling into the

module. Debris that falls into the module could cause damage on powerup.
