Field Installation Guidelines
Ensure proper seating in the VME rack slot with full connector engagement.
Maintain grounding of shielded cables at a single point to suppress EMI.
Route analog signal wiring separately from high-voltage lines to minimize interference.
Confirm terminal board alignment for correct input/output channel mapping.
Reference GEH-6421 manual for installation and configuration procedures.
