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.
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 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 approved personal protective
equipment and insulated tools if working on this drive with
power applied.

Chassis drives
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 inch (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 must be earth grounded. 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
Warning
Do not install, rewire, or remove this control with input
power applied. Doing so may cause fire or serious injury.
Make sure you have read and understood the Safety
Warnings on page i before attempting installation.

12 Installation
•Use 18-24 AWG wire for speed adjust potentiometer wiring. Use
14–16 AWG wire for AC line (L1, L2) and motor (A1 and A2)
wiring.
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 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.
