or
CCW
position for the desired rotation. The
Power
indicator in the
Drive Controls section will be illuminated.
F. Verify that the coaxial plug is fully inserted in the External Power Input of the
unit.
G. Verify that AC voltage is present in the AC outlet to which the AC/DC Power
Supply/Converter is connected.
H. Verify the DC voltage at the 2.5 mm coaxial connector. Must be at least 13
volts DC.
AC/DC Power Supply/Converter is not a serviceable unit and
contains no user serviceable parts.
I. If none of the above solutions work, contact your authorized dealer for

volts DC.
J. Verify the polarity of the DC voltage at the 2.5 mm connector. The sleeve
is negative, the center is positive.
The drive is protected against polarity
reversal and will not operate if the polarities are reversed.
