• The unit tolerates vibration of 0.5 G or less during operation.

Installation Guide

• Mount the A02B-0309-B522 in a clean control cabinet with adequate airflow and space.
• Feed 24 VDC ±10% power from a supply rated above 1.5 A to avoid voltage drop.
• Connect the RS-232C device to the JD36A port with a shielded serial cable.
• Link digital I/O units through the JD51A port using a proper I/O Link cable.
• Connect the Ethernet host to the CD38A port for network data transfer.
• Keep signal cables away from high-power lines to reduce electrical interference.
• Check all connectors and terminal screws before you power up the machine.
• Verify communication and I/O signals through the CNC diagnostic screen after startup.
