Lead Length Specifications
Adhere to the NEC and any local codes during the
installation of ASD/motor systems. Excessive lead
lengths may adversely effect the performance of the
motor. Special cables are not required.
lists
the suggested maximum lead lengths for the listed
motor voltages. Lead lengths from the ASD to the
motor in excess of those listed in
require filters to be added to the output of the ASD.
Figure 7. The Grounding Capacitor Screw is
used on typeforms — 460-volt 175 HP and
above.
The value may be set to Large or Small (default
setting) by placing the screw in the A position or
by placing the screw in the B position,
respectively.

Note:
Contact the TIC Customer Support
Center for application assistance
when using lead lengths in excess of
those listed.
Exceeding the peak voltage rating or
the allowable thermal rise time of the
motor insulation will reduce the life
expectancy of the motor.
When operating in the Vector
Control mode the carrier frequency
should be set to 2.2 kHz or above.
