A. Warranty - LEESON Electric warrants that its products will be free from defects in
material and workmanship for a period of one (1) year from the date of shipment
thereof. Within the warranty period, LEESON will repair or replace such products that
are returned to LEESON or to the nearest Branch Office, with shipping charges
prepaid. At our option, all return shipments are F.O.B. LEESON or its Branch Office.
This warranty shall not apply to any product that has been subject to misuse,
negligence, or accident; or misapplied; or repaired by unauthorized persons; or
improperly installed. LEESON is not responsible for removal, installation, or any other
incidental expenses incurred in shipping the product to or from the repair point.
B. Disclaimer - The provisions of Paragraph A are LEESON’s sole obligation and
exclude all other warranties of MERCHANTABILITY or use, express or implied.
LEESON further disclaims any responsibility whatsoever to the customer or any other
persons for injury to person or damage or loss of property of value caused by any
product that has been subject to misuse, negligence, or accident, or misapplied or
modified by unauthorized persons or improperly installed.
C. Limitations of Liability - In the event of any claim or breach of any of LEESON’s
obligations, whether expressed or implied, and particularly of any claim of a breach of
warranty claimed in Paragraph A, or of any other warranties, express, or implied, or
claim of liability that might, despite Paragraph B, be decided against us by any lawful
authority, LEESON shall under no circumstances be liable for any consequential
damages, losses, or expense arising in connection with the use of, or inability to use,
LEESON’s product for any purpose whatsoever. An adjustment made to the warranty
does not void the warranty, nor does it imply an extension of the original one (1) year
warranty period. Product serviced and/or parts replaced by a no-charge basis during
the warranty period carry the unexpired portion of the original warranty only.
If for any reason any of the forgoing provisions shall be ineffective, LEESON’s liability
for damages arising out of its manufacture or sale if equipment, or use thereof, whether
such liability is based on warranty, contract, negligence, strict liability in tort, or
otherwise, shall not in any event exceed the full purchase of such equipment.
Any action against LEESON based upon any liability or obligation arising hereunder or
under any law applicable to the sale of equipment or the use thereof must be
commenced within one year after the cause of such action arises.

Safety Warnings
•This symbol denotes an important safety tip or
warning. Please read these instructions carefully before
performing any of the procedures contained in this manual.
• DO NOTINSTALL, REMOVE, OR REWIRETHIS
EQUIPMENT WITH POWER APPLIED. Have a qualified
electrical technician install, adjust and service this
equipment. Follow the National Electrical Code and all other
applicable electrical and safety codes, including the
provisions of the Occupational Safety and Health Act
(OSHA), when installing equipment.
•Reduce the chance of an electrical fire, shock, or explosion
by proper grounding, over-current protection, thermal
protection, and enclosure. Follow sound maintenance
procedures.
Warning
It is possible for a drive to run at full speed as a result
of a component failure. LEESON strongly recommends
the installation of a master switch in the main power input
to stop the drive in an emergency.
Circuit potentials are at 115 VAC or 230 VAC above earth
ground. Avoid direct contact with the printed circuit board
or with circuit elements to prevent the risk of serious injury
or fatality. Use a non-metallic screwdriver for adjusting the
calibration trimpots. Use insulated tools if working on this
drive with power applied.

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.

SPEEDMASTER™ OPERATION MANUAL
Installation
Mounting
174102, 174103 and 174107 drives may be vertically wall
mounted using the four 0.19 inch (5 mm) slotted holes on the
attached heat sink (see Figure 1, Page 2). For motor loads less
than 5 ADC, the drive may be bench mounted horizontally, or
operated without mounting.
Removing the Plastic Cover
Connections, calibration, and other settings must be made
internally. After mounting, use the following procedure to remove
the plastic cover and configure the control:
1. Remove the six (6) phillips screws on the front cover. NOTE:
The two shorter screws (#6 - 32 x 2 ½) are for the two lower
holes on the front of the cover (see Figure 2, page 6).
2. Remove the five (5) phillips screws on the bottom plate (see
Figure 2, page 6). NOTE: DO NOT remove the 3 screws
securing the bottom plate to the heatsink.
Line fusing
Line fuses are preinstalled on all 174102, 174103 and 174107
drives. If the horsepower rating of the motor being used is less
than the maximum horsepower rating of the drive, the line fuse
may have to be replaced with a lower rated one. Refer to Table 1
for recommended line fuse sizes.

Warning
Do not connect this equipment with power applied.
Failure to heed this directive may result in fire or serious
injury.
1. Install conduit hardware through the two 0.73” (18.5 mm)
conduit holes or by using aluminum cord connectors attached
to the line seal plate on the bottom of the case.
