SPEEDMASTER™ OPERATION MANUAL

Chassis (uncased) drive installation

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 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 does not have to be earth grounded. If you

choose 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.
