Installation Guide

First, turn off all main electrical supplies before approaching the rack assembly.

Align the 140CPU11302 module straight with the slots on the standard Quantum backplane.

Slide the device smoothly into the designated position until the housing clips lock firmly.

Secure the fastening screws on the top and bottom plates to prevent vibration movement.

Connect the communication cables to the Modbus and Modbus Plus ports carefully.

Verify all grounding connections meet local industrial safety codes before applying power.
