Technical Notes
Changing out from GE 2.3 to Nidec PerfectSpeed DC Motors in the field
The Titus family of Fan Filter Units has previously used the GE 2.3 motor
that was purchased by Regal Beloit. The older models have GE 2.3 motors
that have become obsolete and are replaced with the new Regal Beloit
model EON. The EON motor is currently being evaluated and you will be
receiving a new manufactured motor named Nidec PerfectSpeed.
When you order a replacement motor they will be a form and fit
replacement, except for the cable that connects to the control board and
the motor. The new Nidec motor will require you to replace the cable. The
old cable was a sixteen pin connector while the new motor cable will have
a four pin connector as shown in the photo to the right.
Please use the new cable with the new four pin connector to connect
your new motor. The cable number will be determined by the build style
of your unit.

Old Cable References
The power cable, has remained the same for the new motor and will be
reused. The rest of the fit and function will be a direct replacement. Follow
the procedure in the IOM for motor swap for your particular FFU.
