Applicable Industries

Installation Requirements

1. Insert DMC-1040 into vacant 32-bit PCI 2.2 expansion slot of industrial PC chassis; fasten steel bracket mounting screw to chassis frame
2. Maintain minimum 1 slot empty spacing between DMC-1040 and high-power PCI graphics/DAQ cards for heat dissipation
3. Use double-shielded twisted pair cable for encoder and analog servo wiring; separate signal cables from PC power supply wiring
4. Implement single-point PE grounding of cable shielding at industrial PC cabinet ground bar
5. Install PCI chassis cooling fan to maintain internal chassis temperature below 60 °C during continuous operation
6. Verify PC PCI bus resource allocation before powering on host to avoid bus resource conflict

Operation & Maintenance Precautions

1. Mandatory ESD wrist strap and anti-static mat handling during card installation and removal to prevent PCB static damage
2. Do not bend D-Sub external wiring cables at sharp angles to avoid internal wire fracture
3. Conduct annual inspection of D-Sub connector pins for dust accumulation and oxidation
4. Avoid installation adjacent to high-power switching power supplies inside PC chassis to reduce electromagnetic interference
5. Store spare DMC-1040 cards in sealed anti-static packaging with desiccant packs
6. Fully shut down industrial PC host power supply before disconnecting external D-Sub field wiring cables
