Page 8: Mount The Module
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, Allen-Bradley publication 1770-4.1, for additional information. Mounting Dimensions 90 mm (3.5 in.) - Page 9 Before mounting the module on a DIN rail, close the DIN rail latch. Press the DIN rail mounting area of the module against the DIN rail. The latch will momentarily open and lock into place. Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for vibration or shock environments. End anchor...
- Page 10 MicroLogix 1762-IF4 Analog Input Module Panel Mounting Use the dimensional template shown below to mount the module. The preferred mounting method is to use two M4 (#8) panhead screws per module. M3.5 (#6) panhead screws may also be used, but a washer may be needed to ensure a good mechanical contact. Mounting screws are required on every module.
