Installation Guidelines

CRITICAL WARNING
De-energize the Mark VIe rack, associated terminal board circuits, and all connected field instrumentation before installation or replacement. Verify lockout and tagout procedures are complete. Never insert or remove the I/O pack while system power is present. Confirm that all TMR packs installed on the same terminal board are identical hardware versions before commissioning.

1 Inspect the pack housing, RJ45 ports, and backplane connector for mechanical damage before installation.

2 Verify compatibility with the installed TBAIS1C or STAIS2A terminal board and confirm firmware requirements.

3 Seat the pack fully into the terminal board assembly and verify positive connector engagement without side loading.

4 Connect both Ethernet ports according to the control network architecture and verify network integrity.

5 Apply power and review diagnostic indicators, self-test results, and ControlST status before returning the unit to service.
