Note
Ensure that the motor is only operated when the external fan is running.
Operate the fan only with normal ambient air.
The direction of air flow is from the non-drive end (NDE) to the drive end (DE).
Deposits of contaminated air can impair the heat dissipation of the motor or block the cooling
duct and overheat the motor.
• Position the motor so that the cooling air can freely flow in and out.
• Make sure that no heated discharged air is drawn in.
• Maintain the minimum clearance between the air intake and discharge openings and
adjacent components (see the "Minimum clearance" figure).
• To remove the fan cover and connect the signal connector when the motor is installed,
maintain a minimum clearance of 125 mm.
