Installation Guidelines
-
ESD Protection: This module contains sensitive CMOS components. Always utilize a properly grounded ESD wrist strap when handling the board to prevent electrostatic discharge damage.
-
Power Status: Ensure the control rack is completely powered down before attempting to install or remove the module. Hot-swapping can result in permanent damage to the microprocessor and backplane circuitry.
-
Configuration: Inspect the board for physical jumpers or DIP switches. These must be configured to align with your specific turbine application and site-specific control logic documentation.
-
Maintenance: If cleaning is necessary, use only non-conductive, residue-free electronic-grade cleaners.
