Questions about this item

How do I wire the 4-wire connector on the 9238 fan for 48 V power and PWM control?

Connect the 48 V supply to the red and black leads, feed the PWM signal to the blue wire, and read the tachometer output from the yellow wire; the common mistake is swapping the PWM and tach lines.

Which component of the 9238 fan will need replacement first in continuous 48 V service?

The sleeve bearing inside the 9238 fan is the wear item; when noise or vibration increases, replace the entire 92*92*38 unit.
