connected to a power source (3-phase AC input at the L1, L2, and L3 terminals). The control terminals
of the Q9 F
the proper sensors or signal input sources (see the section titled
for an expanded description of the system control options).
The output terminals of the system (T1, T2, and T3) must be connected to the motor that is to be
controlled. See
As a minimum, the installation of the ASD shall conform to Article 110 of the NEC, the Occupational
Safety and Health Administration requirements, and to any other local and regional industry codes
and standards.

The ambient operating temperature rating for the Q9 F
The process of converting AC to DC, and then back to AC produces heat. During normal ASD
operation, up to 5% of the input energy to the ASD may be dissipated as heat.

enclosure.
Mount the system in a location that is in a well ventilated area that is not in the path of direct sunlight.
When installing multiple ASDs, ensure that there is a clearance space of at least 8 inches (20 cm) from
the top and the bottom of adjacent units. Ensure that the ventilation openings are not obstructed. There
should be at least 5 cm (2 inches) on either side of adjacent units. For the models below 50 HP the top
and bottom clearance specifications may be reduced to 4 inches (10 cm). This space ensures that
adequate ventilation is provided (see the section titled
on pg. 35
Do Not operate the ASD with the enclosure door open.
ASDs produce high-frequency noise — steps must be taken during installation to avoid the negative
effects of noise. Listed below are some examples of measures that will help to combat noise problems.
• Separate the input and output power conductors of the main circuit. Do not install the input and
output wires in the same duct or in parallel with each other, and do not bind them together.
• Do not install the input or output power conductors of the main circuit and the wires of the control
circuit in the same duct or in parallel with each other, and do not bind them together.
• Use shielded wires or twisted wires for the control circuits.
• Ensure that the grounding terminals (G/E) of the ASD are securely connected to ground.
• Connect a surge suppressor to every electromagnetic contactor and relay installed near the ASD.
• Install noise filters as required.
