Applicable Industries

Model Series Belonging

Installation Requirements

1. Mount on standard 35mm DIN rail inside fully enclosed electrical control cabinet
2. Maintain minimum 20mm vertical clearance above and below module for heat dissipation airflow
3. Separate power wiring and signal wiring routing with independent cable ducts to prevent cross interference
4. Ground the metal heat sink base via dedicated PE grounding terminal
5. Ambient installation space humidity must maintain 10% ~ 85% non-condensing

Operation Precautions

1. Prohibit power-on wiring modification; cut off main AC power supply before all wiring operations
2. Do not connect 3-phase AC power supply to single-phase AC input terminal
3. Match motor rated current with driver adjustable output current; avoid long-term full current continuous operation without heat dissipation
4. Prevent metal conductive debris falling into internal circuit cavity during cabinet maintenance
5. If fault alarm LED lights up, cut off power supply and inspect motor winding short circuit, encoder disconnection, over-load stall fault before restart operation
