Installation Guidelines

Ventilation: Due to the 922 W power loss, ensure adequate cabinet ventilation or cooling to prevent overheating, especially when operating near the 50 degC ambient limit.
Cabling: Use shielded cables for motor connections to minimize electromagnetic interference (EMI). Ensure terminals are tightened to accommodate up to 35 mm2 (2 AWG) wire size.
Grounding: Proper earthing of the drive frame is essential for safety and to comply with electromagnetic compatibility (EMC) standards.
Clearance: Maintain the recommended clearance distances around the drive as specified in the manual to ensure optimal airflow through the heat sink.
