Installation Guidelines

CRITICAL WARNING: Risk of equipment damage and electric shock. Always de-energize the entire PLC rack and follow all local Lockout/Tagout (LOTO) procedures before attempting to install, remove, or service any module. This device contains components sensitive to electrostatic discharge (ESD).

1 Ensure the S5 rack is completely powered down and locked out. Verify zero energy state with a calibrated multimeter.
2 Use a properly grounded ESD wrist strap and work on an ESD-safe surface. Unpack the module, avoiding contact with backplane connectors and component leads.
3 Select the designated slot in the S5 chassis. Carefully align the module's card-edge connector with the corresponding backplane socket.
4 Apply firm, even pressure to slide the module into the slot until it is fully seated in the backplane connector. Do not force the module.
5 Secure the module to the chassis by tightening the retaining screws on the front panel. Do not overtighten.
6 After installation is complete and all modules are secured, remove the LOTO device and re-apply power to the system.
7 Observe the module's status indicators (if any) during power-up to verify correct initialization and communication with the CPU.
