HX7+ ASD Installation and Operation Manual 23
Mounting the ASD
Install the unit securely to the floor in a well ventilated area that is out of direct sunlight.
The ambient temperature rating for the HX7+ ASD is from 14° to 104° F or 122° F (-10° to 40° C or

50° C).
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. If installing the ASD in a
cabinet, ensure that there is adequate ventilation.
Do Not operate the ASD with the enclosure door open or with any enclosure panels removed.
When performing maintenance DO NOT insert fingers into the holes of the enclosure.
Note: Ensure that the ventilation openings are not obstructed.
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 electromagnetic contactors and relays installed near the ASD.
• Install noise filters as required.
