Safety Warnings
This symbol denotes an important safety tip or warning. Please read these sec-
tions 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 mainte-
nance procedures.
• It is possible for a drive to run at full speed as a result of a component failure.
Please ensure that a master switch has been placed in the AC line to stop the drive
in an emergency.
• This drive is isolated from earth ground. 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.
