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 the other heat sources. Operate the drive within the speci-
fied 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.
Wiring
Use 18 AWG wire for speed adjust potentiometer wiring. Use 16 AWG wire for motor
wiring.
Twist logic wires (for speed adjust potentiometer) to avoid picking up unwanted electri-
cal noise. Use shielded cable if wires are longer than 18 in. (46 cm).
Keep logic wires away from power carrying lines or sources of electrical noise that
can cause erratic operation. Never run speed adjust potentiometer wires in the same
conduit used for motor and AC line voltage wires.
