On-Site Engineering and Installation Directives

• Electrostatic Grounding Measures: Technicians must secure an approved ESD wrist strap to a verified chassis ground point before handling the circuit board to protect sensitive components.
• Structural Hardware Torque: Mount the board inside the inverter housing frame using original fasteners, tightening structural hardware evenly to exactly 0.6 Nm to prevent micro-fractures in the PCB substrate.
• Ribbon Loom Seating: Inspect all multipin flat ribbon connectors for physical alignment and contamination. Push connectors in until locking tabs click to avoid high-impedance control loops.
• Thermal Pathway Clearance: Maintain clean spacing and verify operational status of local drive cabinet fans during swap-outs, ensuring the ambient temperature immediately surrounding the board remains below 60 deg C.
• Isolation Impedance Testing: Prior to reconnecting primary three-phase utility input power, run a standard insulation test to ensure all signal-level output blocks are completely isolated from high-voltage motor terminals.
