3 SPEEDMASTER™ OPERATION MANUAL
Overview
The following is a quick-step guide to setting up the control. For
more detailed installation information, read the Installation (page
4) and Calibration (page 10) sections of this user’s manual.
1. Mount the control using the 4 slotted holes on the heat sink.
The slotted holes are 0.19 inches [5 mm] (see Figure 1).
2. Remove the plastic cover by unscrewing the 6 screws on the
front cover and 5 screws on the bottom plate. NOTE: Do not
remove the 3 screws securing the bottom plate to the
heatsink.
3. Change the line fuse if necessary. If the horsepower rating
of the motor being used is less than the maximum HP rating
of the drive, the line fuse may have to be replace with a lower
rated one.
3. Wire the control through the conduit holes, or optional
aluminum hardware. NOTE: Do not connect the control
while power is applied.
4. Assure that settings on voltage switches are correct (SW501
& SW502).
5. Apply power to the drive.
5. Calibrate the trimmer pots, if neccessary.
6. Re-install the plastic cover.
