Installation Guidelines
-
Shaft Alignment: Ensure precise alignment with the driven load coupling to prevent premature bearing wear and shaft fatigue.
-
Cable Routing: Utilize the rotatable design of the circular DIN connectors to route cables away from moving parts and sharp edges.
-
Thermal Management: Maintain unobstructed airflow around the motor housing to facilitate natural convection cooling. Do not cover the motor frame.
-
Grounding: Connect the motor's protective ground terminal to the common drive panel ground bus using low-impedance bonding straps.
