To mount the motor be sure to place the lead wire outlet downward. (Adjust the propeller fan and shroud not to contact
with each other).

Fix the motor lead wire onto the motor clamp using a plastic tie as shown in the table on the previous page to avoid
obstructing the propeller fan.

the nut after the shaft screw fully comes out. (Tightening Torque 20 Nm)

lead wire connectors).
