Applicable Industries

Installation Requirements

1. Slide into dedicated Parker CPAR series metal rack slot, lock front module retention buckle fully engaged
2. Maintain minimum 15 mm vertical clearance above and below module for passive heat sink convection cooling
3. Route analog signal cables and digital power/communication cables through separate isolated cable trays
4. Rack cabinet protective grounding resistance ≤4 Ω to suppress industrial electromagnetic interference
5. Install cabinet internal ventilation fan for continuous operation above ambient temperature 50 ℃
6. Do not mount adjacent to high-power frequency converters or high-current contactor assemblies

Usage Precautions

1. Cut rack 24 VDC power supply before plugging/unplugging module to prevent backplane bus short-circuit damage
2. Use shielded twisted-pair wiring exclusively for analog output and encoder feedback signal connections
3. Avoid mechanical impact or liquid spillage onto front terminal block during maintenance operations
4. Strictly prohibit deployment in environments with conductive metal dust or corrosive acid vapor
5. Calibrate analog channel zero offset and full-scale gain every 12 months for long-term motion precision
6. Unauthorized disassembly of internal analog isolation circuits voids all factory warranty coverage
