Safety Warnings
•This symbol denotes an important safety tip or warning.
Please read these sections carefully prior to performing any of
the instructions contained in that section.
• Have a qualified electrical maintenance 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.
It is possible for a drive to run at full speed as a result of
a component failure. Minarik 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 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 approved personal protective equipment and
insulated tools if working on this drive with power applied.

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.

Wiring
• Use 18 AWG wire for speed adjust potentiometer or voltage
signal input wiring. Use 16 AWG wire for motor and AC line
voltage wiring.
• Connect earth ground to the earth ground screw attached to the
PC board. See Figure 2 for the earth ground screw location.

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.
This drive is isolated from earth ground. Circuit potentials are
at 115 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 mya destroy the drive.
