Installation Guidelines
Ensure the system is powered down before connecting or disconnecting the I/O bus cable.
At the Controller chassis, connect the cable to the backplane connector marked "IO bus".
At the I/O chassis, connect the cable to the IO backplane (IOB-0001S/R) at the connector marked "IO bus".
For optimal EMI protection, route the cable along the middle horizontal bar at the back of the housing, keeping it separated from high-voltage power and watchdog cables.
Ensure the latching mechanism is fully engaged to prevent intermittent signal loss.
FAQ
