Safety Warnings

Throughout this manual, this symbol denotes an

important safety tip. Read these sections very carefully!

• 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. To stop the drive in an emergency, ensure

that a master switch has been installed in the AC line.

•This drive is not isolated from earth ground. Circuit

potentials of up to 115 VAC exist on the board.Direct contact

with the printed circuit board or with circuit elements poses the

risk of serious injury or fatality. Use a non-metallic screwdriver

for adjusting the calibration trimpots

Mounting

• Drive components are sensitive to electrostatic fields. Avoid

direct contact with the circuit board. 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 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 must be earth grounded. 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.

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 pg i before attempting installation.
