Installation Guidelines

• Shaft Alignment: Ensure precise alignment between the motor shaft and the coupling device to prevent premature bearing wear and vibration. Avoid excessive radial or axial load limits during mounting.
• Thermal Management: Maintain adequate clearance around the motor frame to facilitate convection cooling. Avoid mounting adjacent to high-temperature heat sources.
• Cable Routing: Avoid applying stress or tension to the power and encoder cables. Keep signal and high-voltage power lines separated in cable trays to minimize electromagnetic interference (EMI).
• Grounding: Ensure the motor frame is securely grounded to the protective earth (PE) terminal of the system control cabinet.
