LIMITED WARRANTY
B. Disclaimer - The provisions of Paragraph A are the Corporation’s sole obligation and exclude all other warranties of MERCHANTABILITY or use, express or implied. The Corporation 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 the Corporation’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, the Corporation shall under no circumstances be liable for any consequential damages, losses, or expense arising in connection with the use of, or inability to use, the Corporation’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, the Corporation’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 the Corporation 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 NOT INSTALL, REMOVE, OR REWIRE THIS 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.

SPEEDMASTER™ OPERATION MANUAL
Chassis (uncased) drive installation
Mounting
• Drive components are sensitive to electrostatic fields. Avoid contact with the circuit board directly. Hold drive by the chassis only.
• Protect the drive from dirt, moisture, and accidental contact.
• Provide sufficient room for access to the terminal block and calibration trimpots.
• Mount the drive away from other heat sources. Operate the drive within the specified ambient operating temperature range.
• Prevent loose connections by avoiding excessive vibration of the drive.
• Mount drive with its board in either a horizontal or vertical plane. Six 0.19 in. (5 mm) wide slots in the chassis accept #8 pan head screws. Fasten either the large base or the narrow flange of the chassis to the subplate.
• The chassis does not have to be earth grounded. If you choose to ground the chassis, use a star washer beneath the head of at least one of the mounting screws to penetrate the anodized chassis surface and to reach bare metal.
Installation

Installation
SPEEDMASTER™ OPERATION MANUAL
• Use 16–20 AWG wire for speed adjust potentiometer wiring. Use 14–16 AWG wire for AC line (L1, L2) and motor (A1 and A2) wiring.
Warning
Do not install, remove, or rewire this equipment with power applied. Failure to heed this warning may result in fire, explosion, or serious injury.
Circuit potentials are at 115 VAC or 230 VAC above ground. To prevent the risk of injury or fatality, avoid direct contact with the printed circuit board or with circuit elements.
Do not disconnect any of the motor leads from the drive unless power is removed or the drive is disabled. Opening any one motor lead may destroy the drive.

Shielding guidelines
Warning
Under no circumstances should power and logic leads be bundled together. Induced voltage can cause unpredictable behavior in any electronic device, including motor controls.
As a general rule, Leeson recommends shielding of all conductors.
If it is not practical to shield power conductors, Leeson recommends shielding all logic-level leads. If shielding logic leads is not practical, the user should twist all logic leads with themselves to minimize induced noise.
It may be necessary to earth ground the shielded cable. If noise is produced by devices other than the drive, ground the shield at the drive end. If noise is generated by a device on the drive, ground the shield at the end away from the drive. Do not ground both ends of the shield.
If the drive continues to pick up noise after grounding the shield, it may be necessary to add AC line filtering devices, or to mount the drive in a less noisy environment.
Logic wires from other input devices, such as motion controllers and PLL velocity controllers, must be separated from power lines in the same manner as the logic I/O on this drive.
