Installation Guidelines

• Safety First: Ensure the drive system is fully de-energized and locked out/tagged out (LOTO) before accessing the power module or replacing the board.
• ESD Precautions: Use an anti-static wrist strap or grounded workstation during handling to prevent damage to the sensitive electronic components on the interface board.
• Precision Handling: Carefully align the board connectors with the power module interface to avoid bent pins or damaged terminal contacts.
• Securing: Tighten all mounting screws to the manufacturer-specified torque to ensure vibration resistance and optimal electrical grounding.
• Verification: After installation, perform a full system diagnostic check via the control unit software to verify communication status before resuming normal machine operation.
