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.

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.

Use approved personal protective equipment and insulated

tools if working on this drive with power applied.

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. Four 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.

Heat sinking

The MM23021 has sufficient heat sinking in its basic

configuration. No additional heat sinking is necessary.

Field output

The field output is for shunt wound motors only. Do not make

any connections to F1 and F2 when using a permanent

magnet motor. See Table 1 for field output connections.

Use 18 AWG wire to connect the field output to a shunt wound

motor.
