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 Analog Output 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.

Page 11: Field Wiring Connections
Analog Output Module Field Wiring Connections Grounding the Module In solid-state control systems, grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI). Run the ground connection from the ground screw of the controller to the ground bus prior to connecting any devices. Use AWG #14 wire. For AC-powered controllers, this connection must be made for safety purposes. - Page 12 Analog Output Module Output Wiring Basic wiring of input devices to the 1762-OF4 is shown below.

Page 13: Wiring The Finger-Safe Terminal Block
Analog Output Module Wiring the Finger-Safe Terminal Block 45161 ATTENTION Be careful when stripping wires. Wire fragments that fall into a module could cause damage when power is applied. Once wiring is complete, ensure the module is free of all metal fragments. When wiring the terminal block, keep the finger-safe cover in place. - Page 14 Analog Output Module Labeling the Terminals A write-on label is provided with the module. Mark the identification of each terminal with permanent ink, and slide the label back into the door. 1762 Expansion I/O Addressing The addressing scheme for 1762 Expansion I/O is represented in the following figure.
