Step 4 Mount the 1769-SM2 module.
Maintain spacing from enclosure walls, wireways, adjacent equipment, etc.
Allow 50 mm (2 in.) of space on all sides for adequate ventilation as shown.
Allow at least 140 mm (5.5 in.) of enclosure depth to accomodate the
1769-SM2 module.
A. Panel Mounting — Mount the 1769-SM2 module to a panel using two
screws per module. Use M4 or #8 panhead screws. Mounting screws are
required on every module.
