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.
