Installation Guidelines

• Cable Routing: Ensure the cable is routed away from high-voltage power lines to minimize potential electromagnetic interference (EMI) on the network signal.

• Bending Radius: Observe the minimum bending radius during installation to prevent internal conductor fatigue or damage to the shielding.

• Connector Security: Ensure the Sub-D9 connector is fully seated and the locking screws are tightened to prevent accidental disconnection due to vibration.

• Network Topology: Verify that the drop cable complies with the total segment length limitations defined by the Modbus Plus network specifications to maintain signal integrity.
