Applicable Industries

Installation Requirements

1. Insert DNC115 into any vacant standard slot of SIGMATEK DIAS DIN rail rack; lock dual side latches tightly to fix module position
2. Maintain minimum 10 mm vertical ventilation gap between DNC115 and adjacent rack modules for heat dissipation
3. Separate Ethernet and DIAS bus communication cables from high-power inverter and motor power wiring with minimum 20 cm clearance
4. Implement single-point PE grounding of all shielded communication cables at cabinet main PE bar; grounding resistance ≤ 4 Ω
5. Verify stable 24 VDC backplane power supply before executing hot-swap replacement of the module
6. Control cabinet internal continuous operating temperature below 55 °C during full-load multi-axis operation

Operation & Maintenance Precautions

1. ESD anti-static wrist strap mandatory during module disassembly, program download and wiring modification
2. Complete full backup of PLC logic and motion parameter files before module replacement to avoid reconfiguration workload
3. Conduct semi-annual inspection of Ethernet and USB port contacts for dust and oxide accumulation
4. Do not install DNC115 adjacent to high-frequency welding equipment and large AC drive inverters
5. Store spare DNC115 modules in sealed anti-static packaging with silica gel desiccant packs
6. Cut off rack backplane 24 VDC power supply before removing the module from DIAS rack slot
