Applicable Industries

Installation Requirements

1. Vertically mount on standard 35 mm DIN rail inside sealed metal industrial control cabinet
2. Maintain minimum 50 mm vertical clearance above and below unit for radiator natural convection cooling
3. Isolate high-voltage power wiring and low-voltage encoder/communication wiring using separate cable ducts
4. Cabinet protective grounding terminal connected with copper wire cross-section ≥2.5 mm², grounding resistance ≤4 Ω
5. Install external forced cooling fan if cabinet internal ambient temperature exceeds 40 ℃
6. Do not mount adjacent to high-power frequency converters or arc-generating contactors

Usage Precautions

1. Cut three-phase mains power supply before connecting or disconnecting motor, encoder and I/O wiring terminals
2. Match external braking resistor resistance and power rating strictly per official datasheet specifications
3. Prevent metal conductive dust accumulation on aluminum radiator fins to avoid heat dissipation failure
4. Do not operate the drive in environments containing acid vapor, oil mist or corrosive industrial gas
5. Execute encoder signal calibration every 12 months for long-term precision positioning stability
6. Unauthorized disassembly of internal power modules voids all factory warranty coverage
