Mount Expansion I/O
Minimum Spacing
Maintain spacing from
enclosure walls, wireways, or
adjacent equipment. Allow
50 mm (2 in.) of space on all
sides for adequate
ventilation, as shown.
Mount Module to Panel
Mount the module to a panel using two screws per module. Use M4 or #8 panhead screws.
Mounting screws are required on every module.
Mount Module to Panel Using the Dimensional Template
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).
During panel or DIN rail mounting of all devices, be sure that all debris,
that is, metal chips or wire strands, is kept from falling into the module.
Debris that falls into the module could cause damage when cycling power.
