Installation Guidelines
- Ensure the control system is powered down before inserting or removing the module from the rack to prevent electrical damage.
- Handle the module using ESD-safe practices to protect sensitive internal components from electrostatic discharge.
- Ensure proper seating in the rack backplane to maintain reliable power and communication connections.
- Route thermocouple signal wiring away from high-voltage power cables and high-EMI sources to maintain signal integrity.
- Verify that the ambient operating temperature remains within the specified 0 to +60 degC range and that adequate ventilation is provided within the control cabinet.
